Additional sizes and body materials of the "PS" line of pilot-operated solenoid valves are now available. Previously offered in Grade 1, Type 1 PVC, the PS valve is now also available in Corzan® CPVC, polypropylene, and Kynar® PVDF in a complete range of sizes from 1/2" through 3". The new valve body materials, in combination with either Viton® or EPDM seals, make the PS suitable for a greater range of high-purity and corrosive liquid applications. This electrically-operated valve is normally-closed and is designed for 1,000,000-plus cycle life in liquid process systems requiring high flow capacity and high pressure capability. With inlet pressure ratings to 140 psi, back pressures to 70 psi and Cv''s from 5.2 to 80, the PS is ideal for controlling flow to spray nozzles, high-pressure chemical injections, batch filling and high volume transfer applications. All available body materials are resistant to both internal and atmospheric corrosion. The valve uses a PTFE Bellows barrier type dynamic seal which prevents fugitive emissions.
