Parker-Sporlan 903050P Head Pressure Control Valve 5/8" ODF 100 PSI LAC-5-100

The Parker-Sporlan 903050P Head Pressure Control Valve is used to regulate discharge pressure operating in low ambient conditions in HVAC systems. It has 100 PSI a 5/8" ODF and uses LAC-5-100. It maintains adequate head pressure by modulating refrigerant flow from the discharge line to the receiver, ensuring stable system performance. It is installed in air conditioning and refrigeration units and supports proper condenser operation, maintains consistent refrigerant feed to the metering part, and prevent issues related to low condensing pressure during cooler outdoor temperatures in HVAC systems.
