Series VCH 2 and 3 port, pilot operated, solenoid valves offer improved durability under a high pressure environment.? Designed for use with air or inert gas, the VCH valve can operate up to a maximum pressure of 5.0MPa.? Large flow passages and ISO 1179-1 conforming port thread sizes of G1/2 to G1 ensure high flow rates, and due to a reduction in the overall volume of the pilot chamber, the VCH's responsiveness can now only be measured in milliseconds.? Non-collision armature construction, rubber buffers and a urethane diaphragm give the VCH series an expected service life of 10 million cycles.
