Sporlan 903038P Pressure Control

LAC-4-180 1/2"ODF 180# CONTROL

Sporlan 903038P Pressure Control Valve (Parker Sporlan LAC-4-180)

The Sporlan 903038P Pressure Control Valve from Parker Sporlan is a high-quality LAC series low ambient pressure control valve designed to maintain proper liquid line pressure in refrigeration and air conditioning systems during low outdoor temperature operation. This non-adjustable valve is factory set and factory tested to ensure reliable, leak-free performance in demanding HVACR applications.

The LAC-4-180 valve limits refrigerant flow from the condenser while simultaneously regulating the bypass of hot gas around the condenser to the receiver. This function helps stabilize system pressures, improve system reliability, and protect components during low ambient conditions.
