Parker Check Valves
Non Return Check Valve (10,000 PSI) - Hi Check Series

Parker's high performance non-return valves can offer the user a cold working pressure rating up to 10,000 psi/689 bar maximum, with a cracking pressure of 10 psi maximum.

Parker's Hi Check series high performance non-return valves are designed for unidirectional flow control of fluids and gases in process instrumentation applications. There is a choice of two check valve models, with cold working pressures of 10000 PSI (689 bar) and 6000 PSI (414 bar). Both check valves have an opening (or ‘cracking') pressure of 10 PSI (0.7 bar). These robust check valves feature a two-piece metal seated body design to minimise any risk of leakage. The Parker check valves are available with a choice of integral male or female NPT, or single- or two-ferrule compression style ends, the compression ends enable users to eliminate the use of taper threads and thread sealant – further reducing the number of potential leakage paths and avoiding system contamination problems. There is a comprehensive range of inlet and outlet connections, covering imperial sizes of 1/4", 3/8” and 1/2", and metric sizes of 6 mm, 10 mm and 12 mm. The check valves are designed to meet the pressure and temperature requirements of ANSI/ASME B.16.34, as limited by the seat materials. NACE compliant versions are available. As standard, Hi Check valves are manufactured from 316 stainless steel, with duplex and monel versions optionally available. For maximum applications flexibility, there is an extensive choice of O-ring materials, including FPM75 and V1238-95 fluorocarbon rubber, Buna-N, ethylene propylene rubber and highly fluorinated fluorocarbon rubber.
