Our 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), commonly known by its popular E.I. DuPont trade name Teflon®, 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 Teflon from DuPont. 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).
