Liebert 127936P2S Low Ambient Control Valve 1/2 Inch

The Liebert 127936P2S is a low ambient control valve designed for precision cooling systems that operate in cold weather conditions. This 1/2-inch valve is a critical component in Liebert Lee-Temp refrigeration control systems, enabling reliable operation of precision air conditioning units when outdoor temperatures drop below standard operating ranges.

Key Features:

• Maintains proper head pressure control during low ambient temperature operation
• Restricts liquid refrigerant flow from the condenser to regulate system pressure
• Enables year-round operation in environments down to -30°F (-34°C) or lower
• Works by flooding the condenser coil with refrigerant to balance condensing requirements
• Essential component for Liebert data center cooling and CRAC systems
• 1/2-inch connection size for refrigerant line integration

This control valve is engineered for use with Liebert precision cooling equipment including Challenger, Deluxe System, and other commercial HVAC units. When outdoor temperatures fall, the valve restricts refrigerant flow to reduce the effective condenser surface area available for heat transfer, maintaining optimal system performance. The valve works in conjunction with heated refrigerant receivers and other Lee-Temp kit components to ensure proper expansion valve operation and prevent low-pressure cutouts during cold weather.

Applications: Data center cooling systems, computer room air conditioning (CRAC) units, telecommunications equipment cooling, and other mission-critical precision cooling installations requiring reliable low-temperature operation.
