Parker Sporlan CROT‑6‑30/110 1/2" SAE Crankcase Pressure Regulator – Premium Compressor Protection
Product Overview
The Parker Sporlan CROT‑6‑30/110 1/2" SAE Crankcase Pressure Regulator is a high‑performance control valve engineered to protect refrigeration and HVAC compressors from overload during startup and heavy load conditions. Designed by industry‑leading manufacturer Parker Sporlan, the CROT‑6 series is known for its reliability, precision, and long service life in commercial and industrial refrigeration systems.
This model features a 30–110 PSI adjustable pressure range and a 1/2" SAE flare connection, making it a versatile and easy‑to‑install solution for technicians and system designers.
Key Features
-
Adjustable 30–110 PSI Range
Allows precise control of maximum crankcase pressure to prevent compressor motor overload. -
1/2" SAE Flare Connection
Standardized connection for quick installation and compatibility with a wide range of systems. -
Protects Compressor During Startup
Limits suction pressure until the compressor reaches stable operating conditions. -
Improves System Reliability
Reduces mechanical stress, extends compressor lifespan, and enhances overall system performance. -
Ideal for Refrigeration & HVAC Applications
Commonly used in supermarkets, walk‑in coolers, freezers, and commercial A/C systems.
How It Works
The CROT‑6‑30/110 regulates suction pressure entering the compressor by throttling refrigerant flow during high‑load conditions—especially during startup or after defrost. By preventing excessive crankcase pressure, the valve ensures the compressor operates within safe limits, reducing the risk of overheating or electrical overload.
