CK3 1" Parker Check Valve

CK3 1" Parker Check Valve

This compact, heavy duty, screw end, in-line check valve is suitable for Ammonia, R-12, R-22, R-502, and other refrigerants, certain oils, and other fluids approved for use in refrigeration. The CK3 is spring closing with a PTFE seat, a zinc plated body and can be installed in any position. The CK3 is available with 1/2", 3/4", and 1" FPT connections. This valve is ideally suited for branch hot gas lines from a single hot gas solenoid valve to prevent liquid crossover between evaporators during refrigeration. They are also recommended for use in the hot gas connection from the drain pan to the evaporator to prevent drain pan frosting.
