White Knight iPolymer Manual Valves

PTFE Ball Valves, Check Valves, Plug Valves, Metering Valves, and Stopcock Valves

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 Manual PTFE Ball Valves

Manual PTFE Ball Valves

iPolymer Ball Valve features an all PTFE wetted surface design. The design is ideally suited for harsh chemical and corrosive media and environments. Polytetrafluoroethylene (PTFE) is ideal for cleanroom and deionized water applications. The body, stem, ball and ports are constructed from PTFE. For standard applications, external non wetted components are constructed from Natural PVDF and Polypropylene.

iPolymer Pneumatic Actuated PTFE Ball Valves

Pneumatic Actuated PTFE Ball Valves

By incorporating an ISO-5211 Mount, our iPolymer Ball Valve are fitted for automatic Pneumatic Actuation. The design is ideally suited for high purity and harsh chemical media. Polytetrafluoroethylene (PTFE) is also well suited to clean room and deionized water applications.

iPolymer Check Valve

PTFE Check Valves

iPolymer Check Valve feature all PTFE wetted surfaces for excellent performance in all high purity applications. Our PTFE design resists chemical corrosion and other elements within a harsh process environments. iPolymer Check Valves are commonly found as backflow preventers in clean processes. They are a simple and ideal device where directional flow control is a must. Depending on the check valve size selected and cracking pressure, some external non-wetted components may include Polypropylene or PVDF. The special internal control spring for 3 psi to 6 psi (nominal 5 psi) cracking pressure is machined virgin PTFE. Whereas, for higher cracking pressures the spring construction is double PTFE Coated Stainless Steel precision ground. Please contact us with your special application requirements. Special PEEK, PVDF and Polypro configurations are available upon request

iPolymer Precision Plug Valves

PTFE Precision Plug Valves

iPolymer Precision Plug Valve (PPV) is a precision machined manual control valve manufactured from PTFE (all wetted surfaces) and PVDF Stem Nut. The PTFE body and stem perform equally well with harsh chemicals and ultra clean DI water. The basic construction is a single through orifice with a tapered body that matches the tapered plug for positive shut-off. Various orifice and port sizes are available as standard items. Other sizes and configurations are available on request. Our Precision Plug Valve are supplied in two configurations: Straight Flow Pattern (“A”) and Angled Flow Pattern (“B”).

iPolymer Metering Valve

PTFE Metering Valves

iPolymer PTFE Metering Valves (MV) use a tapered plug-stem to give a fine adjustment to the flow in addition to a fully open or fully closed shutoff position. The PTFE all-wetted surface design works equally well with ultra clean DI water and harsh chemical media. As with all Metering Valves, we recommend filtering the media prior to entering the valve. Our Metering Valves come in two configurations: Straight Flow Pattern (“A”) and Angled Flow Pattern (“B”).

iPolymer PTFE Stopcock Valves

PTFE Stopcock Valves

Stopcock Valves are precision machined devices that function in much the same way as a ball valve. When the handle points in the direction of flow, the valve is fully open; when the handle points perpendicular to the direction of flow, the valve is fully closed; and at the 45 Degree position the valve is halfway open and thereby has a metering effect on the media flow. iPolymer Stopcock features an all PTFE wetted surface design. The design is ideally suited for harsh chemical and corrosive media and environments. Polytetrafluoroethylene (PTFE) is also well suited to clean room and deionized water applications. The body, stem and ports are constructed from PTFE. For standard applications, external non wetted components are constructed from Polypropylene. All configurations are optionally available as Panel Mounted and/or High Ambient Temperature models.

PTFE Manual Diaphragm Valves

iPolymer PTFE Manual Diaphragm Valves are design for Quarter-Turn manual actuation of our popular Pneumatic and Solenoid configured Miniature Diaphragm Valves. Offered as a 2-Way PTFE Valves, these valves are similar to our Precision Plug Valve. Rather than a stem plug, the valves utilize a flexible diaphragm hard seat seal. As manual valves, they are operated by hand. Used where pneumatic and electrical connections are not practical or not necessary. These Diaphragm Valves provide unsurpassed chemical compatibility with a wide range of media. The all wetted PTFE body, valve stem and one piece diaphragm maintain a material inert boundary for ultra clean applications.

iPolymer PTFE Sampling Metered Valves

PTFE Sampling Metered Valves

iPolymer PTFE Sampling Metered Valves (SMV) are used in high-purity water and aggressive chemical applications. This manually-actuated metering valve provides low flow sampling. The metered flow ensures a controlled dispensing of fluid for manual sampling. It features a PTFE flow path, which is ideal for DI Water Systems and corrosive media for dispensing controlled amounts of media in element verification tests, manual dispensing of DI Water into carboy and other transport containers, and dispensing metered amounts of chemicals to blend and balance process chemistries.
