Description
The Sporlan Controls 903812 1 1/8 Inch Hg Bypass Valve Drhe-6 is a pressure regulating valve used in a variety of HVAC equipment, including refrigeration and air conditioning systems. It works by bypassing hot, high-pressure gas and returning it to the system’s low-pressure suction line. This bypass device keeps the compressor from operating at excessively low suction pressures during times of low cooling demand. Low suction pressures can cause compressor oil dilution and coil icing, reducing system efficiency and lifespan. The Sporlan 903812 Drhe-6 is a direct-acting valve, which means it reacts instantly to changes in suction pressure.
