Refrigerating Specialties CK4A Check Valves (Close Coupled)

These compact valves are spring closing with a lapped, stainless steel or chrome plated seat for positive closing action and low leakage. A minimum pressure difference of 0.05 bar (0.75 psi) is required to hold the valve in the open position. Removable seat plate with combination O-ring and metal-to-metal knife edge seal allows the valve to be disassembled for maintenance. They may be ordered with male adapter rings for close-coupling to other Refrigerating Specialties valves and may be installed in any position.
