Sporlan 903024P Valve 320720-756 this unit is the engineeredThe Sporlan 903024P, also identified as the LAC 4 180, is a heavy duty, non adjustable head pressure control valve designed to maintain consistent system performance during low ambient conditions. This three way low ambient control operates by restricting liquid flow from the condenser to the receiver while simultaneously diverting hot gas to the receiver inlet. This process effectively backs up liquid refrigerant into the condenser, reducing its
