White Knight iPolymer Pneumatic Valves

High-Purity Pneumatic Valves with PTFE Flow Paths

White Knight has acquired iPolymer and is pleased to offer their diverse line of PTFE vales, fittings, spray guns, air cylinders, and other fluoropolymer products.

iPolymer PTFE Pneumatic Diaphragm Valves

iPolymer Miniature Pneumatic Diaphragm Valves offer precision performance under extreme conditions. Options include 2-Way and 3-Way Valves with four body configurations and three valve seat sealing methods. The flow path is 100% virgin PTFE (Teflon) for excellent chemical resistance and high purity integrity.

iPolymer PTFE Chemical-Resistant Valves

iPolmyer Chemical-Resistant (CR) Valves are designed for harsh chemical distribution applications. These valves are manifold style stacked valves. They can be configured up to 15-Ways (Inlet + Outlet). Common for Distribution (one inlet with many outlets) and Selection (many inlets with one outlet). These pneumatically actuated valves are manufactured from PTFE and other fluoropolymers selected for corrosion resistance and chemical inertness within the flow path.

Chemical-Resistant valves offer chemical and corrosion control through a complete fluoroplastic design and construction. All wetted surfaces are manufactured from virgin PTFE. Pneumatic Actuator, Base and Bands are constructed from PVC (standard). The polymer components selected for our iPolymer CR Valve line are specifically suited for use with ultrapure water, deionized water, solvents, chemicals and liquid flowing biomatter. Our PTFE bellows-style valve stem and PTFE valve seat help ensure the valve self-flushes a wide variety of flowing media. Special custom configurations are available on request. These include: manifold valve assemblies with multiple ports and high ambient temperature pneumatic actuators.

iPolymer 2-Way DI Water Valves

iPolymer DI Water Valves are perfect 2-Way valves for wet bench manufactures or any semiconductor facility where ultra pure water is required to flow in a control passage. The DI Water Valve wetted flow path is free of lubricants, elastomers, and springs. Construction include three options for the Body, Piston and Cap Assembly: PVC, Polypropylene or 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 (optional Kalrez). All DI Valve come standard with high performance Stainless Steel actuation springs. This valve replaces the older BECO multi-purpose valves.

iPolymer 2-Way Water Valves

iPolymer Water Valve (WV) is manufactured in three material choices: PVC, Polypropylene, or PVDF. The valve has a spring return and is pneumatically actuated to open or close depending upon the model. The valve is compact and comes with four tapped holes on the base for ease of mounting. This valve replaces the older TEQCOM H2O Valve family.

iPolymer PTFE Pneumatic Valves

iPolymer PTFE Pneumatic Valve (TP Valve) features an all PTFE wetted surface design. The design is ideally suited for harsh chemical and corrosive media and environments. Polytetrafluoroethylene (PTFE) is well suited for clean room and deionized water applications. iPolymer TP Valves, also known as the White Bandit, for its all white style, is manufactured from pure PTFE. The pneumatic actuator housing is design into the main valve body. These valves are excellent for use within wet bench and extreme pH applications (Acid Parts Cleaning, Chemical Delivery, Chemical Neutralization, DI Water Rinse, Phosphoric Acid Nitride Removal, Potassium Hydroxide Etching, Sulfuric Peroxide Stripping, Wafer Etching).

iPolymer Pneumatic Drain Valves

iPolymer Drain Valve (DV) is a large orifice 2-way, 3-way and 4-way drain valve capable of handling large volumes of corrosive fluids via an all non-metallic wetted surface. The valve body components are fabricated from PVC, Polypropylene or PVDF. O-Rings sealing options are EPDM, Viton or Kalrez O-rings. The iPolymer Drain Valve can operate either as air-to-open, air-to-close or air actuated both directions.

All drain iPolymer valves are available in 2, 3 and 4 way configurations with each port operating independently. The “DV” can be operated either by air to open/air to close or by spring return. Either operating method can be specified in the ordering format. Custom configurations available.

For cost efficiency PVC and POL valves are fabricated from PVC or Polypropylene with EPDM or Viton O-rings. PVDF valves maximize performance in ultrapure and harsh chemical environments

iPolymer Quick Dump Valves

iPolymer Quick Dump (“QD") Valves are designed to rapidly drain process tanks. Constructed from high-purity polymers, which are selected to meet your applications needs, our Quick Dump Valves are available in Polypropylene (POL), Polyvinylidene Fluoride (PVDF), Perfluoroalkoxy (PFA) or Polyvinyl Choride (PVC). These valves are designed to be welded directly to the underside (bottom) of tanks. Our Quick Dump Valves are available configured with either O-Ring Seats or Domed Hard Seats. The Domed Hard Seat design prevents ponding/puddling of media on the valve piston and allows for a slight trickle of fluid. This plunger-style valve is very compact, while still configured with optional Air-to-Open/Spring-to-Close or Air-to-Open/Air-to-Close actuation.

iPolymer Dilution Drain Valves

iPolymer Dilution Drain Valves are ideal for cooling and diluting solutions while draining. The valve is designed to shut off the drain automatically if the water flow is interrupted. The DDV fits tanks with 3/8”, 1/2” and 3/4” main drain ports. Main Drain Port & Inlet Port configured to match.
