Pilot-operated solenoid valves
Plast-O-Matic Valves, Inc. announces the availability of additional sizes and body materials in its PS line of Pilot-Operated Solenoid Valves. The valve is now also available in Corzanr CPVC, polypropylene and Kynarr PVDF in a complete range of sizes from 1/2 -3″. The new valve body materials, in combination with either Vitonr 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 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 Cvs from 5.2-80, all available body materials are resistant to internal and atmospheric corrosion. The valve uses a Plast-O-Matic designed PTFE Bellows barrier type dynamic seal that prevents fugitive emissions. The valve has an energy-efficient 11-Watt coil. Positive valve closure occurs in the event of an electrical failure. The molded coil and DIN connector meet NEMA 4X standards. The patented Fail-Dryr design provides advance visual warning of a primary seal.
