700JRX50-C8D Phillips Check Valve, 705-50L Spring, 50 PSI to Open, 3/4 Socket Weld Flanges

The 700X Series flanged in-line piston type check valves are spring closing and can generally be supplied with a 2, 5, 10, 20, 35, 50, 60, 70 and 90 pound differential spring to suit your application. They have a manual lifting stem and replaceable PTFE seat disc. The 700X Series check valves prevent reverse flow of refrigerant in suction, hot gas and liquid lines. These valves are applicable for reciprocating compressor discharge line service, refrigerant pump discharge, suction line service, and can be applied as a hot defrost relief valve. These valves can also be applied as the outlet check valve for various liquid transfer systems. The 700X Series check valve is spring actuated and normally closed. When the differential pressure across the valve is enough to overcome the force of the spring, holding the check valve in the closed position, the disc is forced away from its seat and permits flow. As the differential pressure across the check valve decreases, the disc will be forced back against its seat by the closing spring. All Phillips' check valves may be installed upright in a horizontal line, or vertically in a vertical line.
