Liebert 156400P1S Valve

The Liebert 156400P1S Valve is a direct acting temperature regulator designed specifically for precision cooling applications. This 2-way water regulating valve features a 1/2" pipe connection size and operates on 208/230V power, consuming only 2 watts. Built for 7x24 mission-critical environments, it maintains consistent water pressure and flow to geothermal or water-cooled Liebert Mini-Mate2 and DataMate systems. By accurately modulating flow based on condensing pressure, this OEM Liebert part prevents high-pressure alarms and extends the service life of your compressor by ensuring optimal thermal exchange in server rooms and data centers.

• Precise Head Pressure Control: Automatically adjusts water flow to maintain stable condensing temperatures, preventing system-wide high-pressure trips.
• High Energy Efficiency: Low 2W power consumption and optimized flow rates reduce operational utility costs in 24/7 cooling environments.
• OEM Compatibility: Engineered as a direct replacement for Liebert 156400P1S and obsolete 156400P1 models, ensuring a perfect fit and matched electrical specifications.
• Durable 1/2" 2-Way Design: Robust construction suitable for both potable and non-potable water systems, compliant with low-lead requirements.

• Is this compatible with glycol systems? Yes, the Liebert 156400P1S is frequently used in both water and glycol-cooled condensing units to manage flow through the heat exchanger.
• What does the 2W rating signify? This indicates the electrical draw of the actuator or solenoid component, making it an extremely efficient water regulator valve for commercial HVACR applications.
• Will this valve fix high-pressure alarms in my Mini-Mate unit? If the alarm is caused by insufficient heat rejection due to a stuck or leaking valve, replacing it with a new 156400P1S will restore proper flow and resolve the issue.
