Description
The Sporlan Controls ADRPE Discharge Bypass Valve (SKU 903532) is a precision-engineered refrigeration component designed to maintain stable system operation by automatically bypassing excess discharge gas when system load drops below the compressor’s minimum capacity. With a 5/8″ connection size and a 0–80 operating pressure range, this valve is well-suited for a broad range of light commercial and commercial refrigeration and air conditioning applications.
How It Works
The ADRPE discharge bypass valve senses suction pressure and opens to divert hot discharge gas directly into the low-pressure side of the system. This prevents evaporator freeze-up and compressor short-cycling during low-load conditions, protecting equipment and extending service life.
