Description
The Sporlan Controls 903574 is a 5/8″ discharge bypass valve engineered for precise refrigeration system pressure management. Designed to maintain stable suction pressure and protect compressors from low-load conditions, this valve automatically bypasses hot discharge gas back to the suction side of the system when evaporator load drops below a set threshold — preventing compressor short cycling and ensuring consistent system performance.
Key Features
- 5/8″ connection size for compatibility with a wide range of refrigeration and HVAC systems
- Pressure operating range: 0–80 PSI for versatile low- to medium-pressure applications
- Automatic discharge gas bypass to maintain minimum suction pressure under light load conditions
- Protects compressors from short cycling and low-load damage
- Durable construction built to Sporlan’s industry-leading quality standards
- Designed for use in commercial refrigeration and air conditioning systems
Application
The Sporlan 903574 discharge bypass valve is ideal for commercial refrigeration systems, walk-in coolers, display cases, and air conditioning applications where load variations can cause suction pressure to drop below safe operating levels. By diverting hot discharge gas back into the suction line, this valve stabilizes system pressure and extends compressor life.
