  • Nitrogen and DI Spray Guns Explained

    Posted on by IAC

    Nitrogen and deionized water spray guns perform the same basic function but important differences between the two exist. We outline what those are.

     

    Nitrogen Spray Guns

    Manufacturing and assembling products in a cleanroom environment require specialized equipment to reach specific ISO cleanroom standards. One tool used is the nitrogen spray gun.

    Nitrogen gas is cleaner and drier than conventional air, making it an effective tool for removing microscopic dust and fibers from surfaces that can’t be cleaned by wiping—including environments such as semiconductor fabrication plants and sterile manufacturing facilities. 

    Our nitrogen spray guns are constructed of PTFE, making them capable of working effectively in the presence of moisture, corrosive substances and other traditional agents of deterioration or decay. This makes them ideal for everything from chemical processing to biomedical applications, water purification, sewage treatment, life sciences and similar industries.

    The most common products produced with nitrogen spray guns include semiconductors, medical devices, optical lenses, military, aerospace, food packaging and small electronics. 

    Although most customers typically find that our stock nitrogen spray gun meets their needs, we are fully capable of tailoring your gun to suit your requirements. Our selection of PTFE spray guns is designed to be versatile and outperform the industry standard.

     

    Deionized Water Spray Guns

    Deionized water often is used in semiconductor manufacturing, refined chemical manufacturing, biological development and pharmaceutical production. iPolymer offers an array of DI water spray guns ideal for these applications.

    Our DI spray guns are manufactured with polypropylene and virgin PTFE, which gives them a long service life in corrosive and harsh acidic conditions. As a result of their design and comfortable grip, these spray guns set the industry standard in work processing stations, wet benches and semiconductor fabrication plants.

    Our deionized water spray guns feature a machined PTFE body with precision-machined sealing areas. Coupled with a PTFE interior surface and a one-piece machined polypropylene poppet, our DI Spray Gun provides for considerable leak-proof integrity and exceptional corrosion resistance.

    PTFE is a nonconductive material that provides exceptional resistance to strong electrical fields. Our spray guns also operate well when exposed to hydrofluoric acid, a substance that can dissolve other materials, such as metal and glass, and are resistant to fume attack.

    Recirculating DI water spray guns constantly have a small amount of water flowing through the hose and spray gun, which eliminates stagnant water and prevents the growth of bacteria. 

    The DI water spray gun features a wiper seat, which creates a reliable diaphragm to body seal and provides positive through flow shutoff. Its unique design eliminates the need for elastomer seals, while providing excellent flexibility and long life.



    Features and Benefits of iPolymer Spray Guns:

    • One-piece machined PTFE body and polypropylene poppet provide high flexural life and exceptional corrosion resistance
    • Fully functional from 0 to 75 psig
    • Optional recirculation kit is available for low dead volume, high purity, and reliable circulation
    • Fluid temperature range: 40°F to +130° F (4°C to +54° C)

  • Uses & Benefits of DI Water Valves

    DI water valves

    Deionized water, or “DI water” is a mineral-free solution that absorbs ions on contact, eliminating calcified and corrosive buildup. It is used to clean, lubricate, dilute, and cool process media in high-purity systems without introducing contaminants. iPolymer DI water valves are ideal for semiconductor, biomedical, and food and beverage manufacturing, in which ultra-pure water is required to flow in a control passage.

    DI WATER VALVES | FEATURES AND BENEFITS

    iPolymer DI water valves are perfect 2-way valves for wet bench manufacturers. The DI water valve wetted flow path is free of lubricants, elastomers and springs.

    Construction includes three options for body, piston and cap assembly: PVC, Polypropylene and PVDF. For the highest level of chemical inertness and overall fluid handling performance, all three configurations include 100% Virgin PTFE for the bellows and backing plate construction. O-ring seal options include EPDM or Viton. Every DI valve comes standard with high-performance stainless steel actuation springs.

    Depending on the model chosen, the DI valve is actuated pneumatically to close or open.

    DI Water Systems

    At iPolymer, we manufacture numerous products for purified water processing and DI water systems. Within these systems we apply high-purity polymers that don’t introduce ion particles in the water flow path. The use of these polymers prevents the development and spread of bacteria and viruses and facilitates excellent chemical inertness within the media.

  • Advantages and Disadvantages of PTFE Ball Valves

    ptfe ball valve

    Valves are critical components in any industrial piping system. Of the many valve types, ball valves offer unique characteristics to control flow.

    Ball valves are made up of a limited number of components, primarily: stem, stem nut, ball and body.  From a Failure Mode & Effect Analysisactuated ball valve (FMEA), the low component count greatly increases the ball valve’s mean time between failure.  Ball valves are known for their robust durable characteristics and reliable performance.  The most crucial component is the ball valve seat, which serves two functions: uniformly distribute the pressure induced stresses and maintain a good fluidic seal.

    Ball valves commonly are used as main shutoff or blocking valves in HVAC systems, chemical and water distribution systems, oil and gas process systems, food and sanitary process facilities, and pharmaceutical OEM devices.

    PTFE ball valves, like those engineered by iPolymer, feature an all-wetted surface design, ideally suited for harsh chemical and corrosive media, cleanroom and deionized water applications.

    In this post, we consider the advantages and disadvantages of PTFE ball valves.

    Advantages of PTFE ball valves:

    • Require no lubrication and provide a tight seal with minimal torque. Because they require no lubrication, ball valves also can be used in corrosive media and without the potential for contamination.
    • Provide fast, shock-free opening and closing and fully seal under a wide range of pressures and temperatures.
    • Offer a long, maintenance-free service life. When a ball valve requires repairs, seats are easily accessible.
    • Lightweight, and simple to install and operate. Ball valves also are a lower-cost solution compared to alternative valve types.
    • Can be used in a wide range of industrial applications—particularly when strict maintenance and regulation of pressure and volume is required.

    ball valve

    That said, there are some drawbacks to PTFE ball valves.

    Disadvantages of PTFE Ball Valves:

    • PTFE has higher expansion coefficient, sensitivity to cold plastic flow and comparatively poor thermal conductivity (good insulator). If the sealing surfaces are scratched, reliability of the seal decreases.
    • While PTFE material can handle extreme temperatures, the thermal expansion properties will limit the useful temperature range (due to device assembly tolerances). For normal use, temperature swings should remain below 180°C.
    • Regulating performance is generally less than that of pneumatic valves.
    • Can underperform when used to regulate improper fluids, such as slurries containing solids, which can lead to wear, damage and jams.
    • Not recommended for use in applications requiring sustained throttling.

    Valves perform essential functions in every industrial piping system. iPolymer’s knowledgeable staff ensures you’ll get the right components for your system. Give us a call at 435.783.6040 for more information, or request a quote if you already know what you need.


  • How High-Purity Corrosion-Resistant Valves Make Life Easier

  • Custom Manifold Designs for High Purity Valve Applications

    high purity valve

    Valve manifold assemblies control fluids or gases throughout piping systems—from entry to exit ports—consolidating production processes to enhance product quality and system efficiency. They are widely used in high-purity semiconductor, pharmaceutical, biomedical and chemical process applications.

    Valve manifold assemblies allow for easy traceability of all components for consistent, quality performance. Without their use, applications would require independent delivery systems for every point—resulting in inefficiencies, including fewer quality controls; greater space requirements; and higher costs.

    Several system factors determine the valve manifold assembly best suited to your application. They include:

    • The valve manifold assembly must be compatible with the fluid or gas moving through the system.
    • The valve manifold assembly must be designed to accommodate the flow intake while also achieving the flow rate demands downstream. Same is true of pressure throughout the source lines.
    • The valve manifold assembly must be suited to the material temperature.

    iPolymer valve manifold assemblies offer precision performance under extreme conditions and are suitable for a wide range of ultra-clean to highly corrosive media applications. Our chemical-resistant valves and valve manifold assemblies provide dependable action that can be tailored to suit your specific operational needs.

    iPolymer valve manifold assemblies provide unsurpassed chemical compatibility within a wide range of flow media. Their all-wetted PTFE body and valve stem maintain a material inert boundary for ultra-clean applications and challenging environments.

  • PTFE Pneumatic Valves vs. PTFE Solenoid Valves

    Pneumatic and solenoid valves perform the same basic function: They modulate flow within industrial systems. But that doesn’t mean they are interchangeable. Installing the correct valve, constructed of the proper material, will determine whether your system functions or fails.

    Pneumatic Actuation vs. Solenoid Actuation

    While PTFE valve bodies are almost identical, the actuation is fundamentally different.

    • PTFE pneumatic valves are actuated by a pneumatic actuator. The media working pressure for PTFE pneumatic valves can be greater because pneumatic actuators can generate larger forces and handle drive pressures (from 60psi to 100psi). The rate of actuation, speed of opening and closing, is 280ms to 450ms. Pneumatic actuators can drive PTFE valves as small at 1/16 inch to larger than 2 inches.
    • PTFE solenoid valves are actuated by way of a solenoid actuator. Media working pressures are limited due to the strength of the magnetic field generated by the solenoid coil (which in turn creates the pulling force). The rate of actuation, speed of opening and closing, is much faster: 90ms to 190ms. The solenoid actuator limits the size of the available PTFE valve up to ½ inch.
    • Another key difference between PTFE pneumatic valves and PTFE solenoid valves is how they are controlled. Solenoid valves can take a direct electrical signal from a controller or an indirect electrical signal from a power relay. The majority of time the user will include a small pneumatic air valve to trigger the compressed air, which will ultimately drive the PTFE pneumatic valve.

     

    The Basics of PTFE Pneumatic Valves

    chemical resistant valve

    Pressurized air, from the facility’s air compressors, should be filtered and dry before use within pneumatic devices. This compressed air is referred to as CDA. Automation system valves are signaled to open and allow the CDA compressed air to flow to the PTFE pneumatic valve. Once the inrush of air pressure becomes strong enough, it pushes against the actuator piston and actuator spring, moving the valve diaphragm and thereby opening or closing the valve. When air is exhausted, the valve actuation assembly moves in the opposite direction.

    Our iPolymer PTFE Pneumatic Valve line features an all-PTFE wetted surface design ideally suited for harsh chemical and corrosive media and environments, as well as clean room and deionized water applications. The pneumatic actuator housing is designed into the main valve body for use within wet bench and extreme pH applications, such as:

    • acid parts cleaning
    • chemical delivery
    • chemical neutralization
    • deionized water rinse
    • phosphoric acid nitride removal
    • potassium hydroxide etching
    • sulfuric peroxide stripping
    • wafer etching

     

    The Basics of PTFE Solenoid Valves

    Solenoid valves consist of a coil, plunger and diaphragm assembly and are most commonly used to control the flow of liquid or gas. In a closed valve system, a spring holds the plunger in place to prevent flow. Once the solenoid coil is energized, the magnetic field raises the plunger to enable flow. The opposite is true in an open valve system. Solenoid valves are quick to open and close, and generally are used in smaller-diameter systems.

    The all-PTFE wetted surface design of our solenoid valves is suitable for a wide range of ultra-clean to highly corrosive media applications—making them ideal for use in semiconductor, pharmaceutical, biomedical and chemical process applications.

    Highlights:

    • PTFE design optimized for ultra-clean and chemical compatibility;
    • Available for DC & AC voltages;
    • Fast, accurate and repeatable coil response time;
    • High-duty cycle rated with controlled ambient temperatures;
    • Valve seat and diaphragm for positive flushing and tight shut off;
    • Nonporous diaphragm isolates solenoid coil from media;
    • Designed for aggressive media and elevated temperatures.

  • Why Valves Deserve Greater Attention in Industrial Piping Systems

    Consider the many virtues of valves.

    They regulate temperature and prevent backflow contamination. Create precise mixtures. Control pressure and stress. Ensure safety in the event of system failure.

    And yet, valves often are among the last considerations when designing an industrial piping system. One possible explanation: Valves are among the cheapest components to buy and install—leading many to underestimate their overall importance.

    And yet installing the correct valves, made of the proper material in the right configuration will determine whether a system succeeds—or fails. Performs as you need—or represents a costly mistake.

    We run through the most common valve configurations and how they work.

     

    sub miniature PTFE solenoid valves
    iPolymer subminiature solenoid valves

    Solenoid: electro-mechanical valve consisting of a coil, plunger and sleeve assembly most commonly used to control the flow of liquid or gas. In a closed valve system, a spring holds the plunger in place to prevent flow. Once the solenoid coil is energized, the magnetic field raises the plunger to enable flow. The opposite is true in an open valve system.

     

    chemical resistant valve
    iPolymer pneumatic diaphragm valves

    Pneumatic: used to control or modulate airflow. Common types of valves used within pneumatic systems include:

    • Pressure Relief Valves control pressure by opening and closing the chamber through which pressurized air moves. Pressure relief valves are a fail-safe to prevent equipment failure.
    • Flow Control Valves control air velocity from the actuator, the part within pneumatic systems that converts air pressure into motion.
    • Quick Exhaust Valves consist of an input, an outlet and an exhaust to provide a rapid exhaust of controlled air.
    • Directional Control Valves change the direction of pressurized air and show the number of positions, methods of actuation, number of ports and paths air can take.

     

    ptfe-ball-valve
    iPolymer PTFE ball valves

    Manual: primarily used to stop and start flow through the use of a handwheel or lever. Common manual valves include:

    • Ball: uses a pivoting ball to control liquid flowing through a system.
    • Check: allows fluid to move only in one direction only, primarily to prevent backflow.
    • Precision Plug: features a manual adjustment knob with fine threads to precisely set desired flow rate.
    • Metering: uses a tapered plug-stem to finely adjust flow.
    • Stopcock: features a handle that points in the direction of flow, often used for chemical fluid and gas shutoff.
    • Diaphragm: features a flexible diaphragm for hard-seat seal and typically used where pneumatic and electrical connections are not practical or necessary.

    The material used in constructing valves depends on the type of fluid or gas running through your industrial piping system.

    When working with high alkaline media (high pH) or high acidic media (low pH), extra care must be taken, as depicted in the graphic. The pH Scale ranges from 0-14, with zero representing a highly acidic media and 14 representing a highly alkaline media. Both extremes can be very corrosive to piping, tubing, fittings, filters, pumps, tanks and valves. These types of systems typically require components constructed of high-purity polymer.

  • Continuous Temperature Monitoring of your High Purity Process

    iPolymer’s PFA protected Thermocouple Sensor Unions are introduced through inline fittings—offering easy, space-saving installation into existing or new flow paths.

    Maintaining tightly controlled temperatures is critical during manufacturing processes across high-tech, life-science and chemical industries, where even minute fluctuations in temperature can spell ruin for fragile components—if not prove fatal.

  • The Basics of Pneumatic Valves

    iPolymer Valves

    Shown: Stopcock (SC-503-P), Pneumatic Actuated Valve (MTV-422CFS-T), Metering Valve (part number not shown), Solenoid Valve (M223W1AFS-HT-132), Ball Valve (BV-44-P).

    Stopcocks, Metering Valve and Ball Valves are examples of Manual Valves. The MTV is one of about five families of pneumatically actuated valves. The blue top valve is the Solenoid Valve. It comes in two basic sizes: mini and submini. Within those sizes are several unique configurations.

    Many iPolymer valves vary by attachment ports size and style: 2- or 3-way, and how they actuate (i.e. manual, pneumatic and/or solenoid).

    Bicycle pumps, dental drills and jackhammers all have one thing in common: They are everyday examples of pneumatic machines.

    Even in industrial settings, where pneumatic systems run complex functions, pneumatic machines of all types use the same components to generate and use compressed air to perform. They are:

    • Compressor
    • Reservoir
    • Valve

    Although compressors and reservoirs can vary, their basic functions do not: They create and hold pressurized air. The same cannot be said of valves. All valves used in pneumatic systems control or modulate airflow based on the needs of the system, but there are several configurations to consider.

    The Basics of Pneumatic Valves

    Below are the most common types of valves used within pneumatic systems.

    Pressure Relief Valves:

    Pressure relief valves do exactly as the name suggests: They control pressure by opening and closing the chamber through which pressurized air moves. They automatically open at a set pressure and automatically close once air pressure drops below a specific point. Pressure relief valves are a fail-safe to prevent equipment failure resulting from excess pressure caused by such things as temperature increases and control valve malfunction.

    Flow Control Valves:

    Flow control valves control air velocity through pneumatic systems and are useful for controlling flow rate from the actuator, the part within pneumatic systems that converts air pressure into motion. Flow control valves adjust airflow in one direction, allowing air to flow freely in the opposite direction. Check valves, a type of flow control valves, allow air or gas to move in one direction only to prevent backflow.

    Quick Exhaust Valves:

    Quick exhaust valves consist of an input, an outlet and an exhaust. Quick exhaust valves work by providing a rapid exhaust of controlled air when placed directly onto an air cylinder after the control valve.

    Directional Control Valves:

    Directional control valves change the direction of pressurized air.

    Two-, three- and four-way valves are common in industrial pneumatic systems. Directional control valves show the number of positions, the methods of actuation, the number of ports and the paths air can take.

    Valves perform essential functions in every pneumatic system. Our knowledgeable staff has years of experience to help you get what you need. Give us a call at 435.783.6040 or request a free quote.

    iPolymer manufactures a range of chemical-resistant valves that provide a cost-effective, efficient solution suitable for use in many industries. 

    Discover iPolymer’s Range of Chemical Resistant Valves

    We offer a wide selection of chemical-resistant values to meet your requirements.

    From a design standpoint, chemical-resistant valves are pretty much any type of valve that offers good performance in chemical applications. More common commodity valves, manufactured from low-grade plastic, steel or aluminum, will not hold up against high and low pH chemistries. When the media (liquid or gas) has a corrosive nature, such as, sulfuric acid, the application calls for a chemical-resistant valve.

    chemical resistant valves

    An acid rated at pH 2 is much more corrosive than a mild acid with a pH of 5. In fact, 1,000 times. Unfortunately, it isn’t quite this simple, but 0, 1, 2 and 12, 13, 14, you are most likely going to use PTFE devices. Mild pH 5, 6, 8, 9, you can use polypropylene or PVC devices. Raw PTFE material cost 350% more than polypropylene and PVC.

    The iPolymer Chemical-Resistant Valve product line, also known as our CR Valve product line, is a specific design configuration. Our CR Valve line is a linear manifold family of valves, which can be configured with one inlet and up to 13 outlets (or the reverse: one outline and up to 13 inlets). One inlet feeding up to 13 outlets would be considered a distribution configuration. One outlet fed by up to 13 inlets would be considered a selection configuration.

  • Effective Check Valve Selection for Chemical Process Systems

    Posted on by IAC

    Utilized across a wide array of industries, such as: water, semiconductor, pharmaceutical, food and beverage, chemical, and more, chemical process systems are an essential part of transferring fluid media across various stages of manufacturing. Within the chemical process systems, there are specialized PTFE Check Valves which work to help direct flow control. PTFE Check Valves are used to ensure free flow in one direction and checked (no flow) in the opposite direction. iPolymer is your global source for advanced high purity fluid handling products, including PTFE Check Valves. Our high purity check valves are offered in a wide range of sizes and options.

    PTFE Check Valve

    Selecting the proper PTFE Check Valve for a high purity chemical application requires considerations of the valve size, materials, and cracking pressure. The most common material we used for high purity applications is PTFE. Given PTFE’s great resistance to corrosion, excellent temperature resilience, and inert behavior during fluid/gas transfer, it stands out among other polymers in the high purity arena.

    Spring energized check valves can be oriented both vertically and horizontally. The internal spring ensure the check valve’s poppet will reengage and seal once cracked open for directional flow. Whereas ball check valves without springs, should be oriented vertically with direction flow upward against gravity. Gravity and the fluid column act as the spring and ensure the ball closes off the flow path.

    iPolymer offers a wide range of PTFE Check Valve configurations. Custom orifice sizes, port sizes, end connection designs, and cracking pressures are all features to discuss. Our valves are commonly found as backflow preventers in clean processes where directional flow control is a must. We offer two configurations for our internal control springs, depending on the cracking pressure. For lower cracking pressures applications, at a nominal 3 to 5 psi, we utilize an internal spring manufactured from virgin PTFE. For higher cracking pressure applications, our check valves are constructed with a Teflon-Coated Stainless Steel, Carpenter-20, Inconel, or Hastelloy springs. The metallic spring selection is dependent on the chemical media and application parameters. iPolymer PTFE Check Valves are available from 1/8” to 1” and with a variety of common end connections.

    At iPolymer, it is our goal to provide an exceptional selection of engineering high purity fluid handling products, including our PTFE Check Valves. Our staff will work with you to understand your unique application and will help to select the proper valve solution. Interested in learning more?

  • How Do PTFE Pneumatic Valves Work

    Posted on by IAC

    Commonly utilized in an assortment of applications that rely on compressed air to drive an actuator attached to the valve, Pneumatic PTFE Valves are used in numerous industrial application, including food and beverage production, chemical processing, oil and gas processing, and chemical distribution in semiconductor applications.

     

    The primary function of this type of valve is to block or divert the media flow.  Rather than manually hand turning the valve on or off, or manually diverting the media flow from port A to port B, Pneumatic PTFE Valves are automated.  The client’s control system trigger compressed air to actuate the valve remotely.

     

    iPolymer offers an impressive selection of pneumatic valves, including pneumatic diaphragm valves, chemical resistant pneumatic valves, 2-way pneumatic water valves, Teflon pneumatic valves, pneumatic drain valves, pneumatic quick dump valves, pneumatic dilution drain valves,  

    and pneumatic diverter valves. Every valve we produce is designed to meet strict quality and sanitation standards for use in engineered high-purity fluid handling applications.

     

    So, how do these valves work?

     

    There are several different types of pneumatic valves, with almost every version using the same basic principles for actuation.  There are two major subcomponents within all PTFE Pneumatic Valve assemblies: 1) the PTFE Valve and 2) the Pneumatic Actuator.

     

    The variation within the PTFE Valve is driven by the application.  Clients work with iPolymer Application Engineering daily to identify standard catalog and custom solutions for their applications.  PTFE Valve body design considerations include; 2-Way, 3-Way, or manifolded multi-way; flare, compression tube, or NPT ports; diaphragm, bellows, or plug style orifice sealing; and other design features to optimize for the application at hand.

     

    The Pneumatic Actuator is a simple addition to the top of the valve body.  Rather than configuring for manual (by hand) opening and closing of the valve.  The valve is remotely actuated with a special air cylinder.  The air cylinders (“Pneumatic Actuators”) are configured to drive in a linear or rotational fashion depending on the actuation needs of the attached valve.

     

    iPolymer is highly-regarded as one of the best worldwide suppliers of high-purity fluid handling equipment. We routinely engineer stock and custom pneumatic valves, for customers involved in high-stakes industries like chemical processes and life sciences.
