Description
Parker-Sporlan CROT-6 Crankcase Pressure Regulating Valve
The Parker-Sporlan 900365P CROT-6 is a crankcase pressure regulating (CPR) valve engineered to protect refrigeration and air conditioning compressors from dangerously high suction pressures during system pulldown and startup. By limiting the suction pressure entering the compressor, the CROT-6 prevents motor overloading and extends compressor service life — a critical safeguard in commercial refrigeration systems.
Key Features
- Model: CROT-6 crankcase pressure regulating valve
- Pressure range: 30–100 PSIG
- Connection size: 7/8″ ODF sweat
- Limits suction pressure to protect compressors during high-load pulldown conditions

Application
The CROT-6 is ideal for installation in the suction line between the evaporator and the compressor. It is commonly used in walk-in coolers, reach-in display cases, and other commercial refrigeration systems where compressor protection during high-load startup is required. The 30–100 PSIG adjustable range provides flexibility across a variety of refrigerant applications and system configurations.
