Sporlan Controls 903029 LAC-5-180 Head Pressure Control Valve 5/8" ODF 180 PSI

The Sporlan Controls LAC-5-180 is a professional-grade head pressure control valve designed for commercial and industrial refrigeration systems operating in low ambient conditions. This three-way valve maintains optimal head pressure during cold weather operation by restricting liquid refrigerant flow from the condenser while simultaneously diverting hot gas to the receiver.

Key Features:

• Pressure range: 180 PSI receiver pressure setting
• Connection size: 5/8" ODF (copper sweat connections)
• Brass body construction with copper fittings for durability and corrosion resistance
• Non-adjustable, factory-calibrated design ensures consistent performance
• Design working pressure: 450 PSI for LAC-5 series
• Compatible with R-22, R-134a, R-404A, R-507 and other common refrigerants
• Factory tested for leak-free operation

This valve prevents common low-ambient problems including insufficient head pressure, low suction pressure, iced evaporator coils, and refrigerant migration during off-cycles. By flooding the condenser and raising receiver pressure, the LAC-5-180 allows refrigeration systems with air-cooled condensers to operate normally even when outdoor temperatures drop significantly. Part of the trusted Sporlan LAC series, now manufactured by Parker Hannifin.
