Liebert 1C21207P5 322056-301 This rugged HVAC zone valveThe Liebert 1C21207P5 is a high performance Low Ambient Control Valve engineered to maintain critical head pressure in air cooled condensing units during low temperature operations. Specifically designed as the direct replacement for the Y1188 LAC 4 180, this three way modulating valve responds to discharge pressure to ensure consistent refrigerant flow to the expansion device. By backing up liquid refrigerant into the condenser, it effectively
