Parker Hannifin CROT-6 5/8" SAE Crankcase Pressure Regulator (0 to 60 psi)

Crankcase pressure regulating valves are designed to prevent overloading of the compressor motor by limiting the crankcase pressure during and after a defrost cycle or after a normal shutdown period. When properly installed in the suction line, these valves automatically throttle the vapor flow from the evaporator until the compressor can handle the load.
