Sporlan 903112 Pressure Control R-407C The 78H4001 is often theThe Sporlan 903112, also identified as the LAC 5 295HP 1 2ODF, is a non adjustable low ambient head pressure control valve designed to maintain system stability in air cooled condensers. In cold weather, this valve modulates to restrict liquid flow from the condenser while simultaneously bypassing hot gas into the receiver. This action backs up liquid in the condenser to reduce its effective surface area, ensuring the condensing pressure remains high
