Sporlan 903031P Pressure Control R-410A ensuring a direct mechanical fitThe Sporlan 903031P Pressure Control Valve, also identified as the Parker Sporlan LAC 4 100, is a high performance low ambient head pressure control designed for small capacity refrigeration and air conditioning systems. This three way modulating valve maintains stable liquid line pressure by restricting refrigerant flow from the condenser while simultaneously bypassing hot gas directly to the receiver during low outdoor temperatures.
