Relief, Pilot Operated
ValveTech has developed a line of low pressure, in-line, pilot operated relief valves. The valve design incorporates elastormeric seats for conventional environments and Kel-F seats for cryogenic operation. Materials of construction include aluminum, stainless steel and inconel. The valve is capable of very precise crack and reseat pressures with very little hysterisis over temperature and pressure. End fittings include Gamah, PSI and Hydraflow couplings.
