Liebert 176251G1S Thermostatic Expansion Valve (TXV) for Precision Cooling Systems

The Liebert 176251G1S is an OEM replacement Thermostatic Expansion Valve (TXV) designed for use in Liebert precision cooling and Computer Room Air Conditioning (CRAC) systems. As a critical refrigerant metering component, the TXV precisely regulates the flow of liquid refrigerant entering the evaporator coil, maintaining optimal superheat and protecting the compressor from flooding or overheating.

Key Features:

• OEM Liebert replacement part — direct drop-in for compatible precision cooling units
• Thermostatic expansion valve precisely meters refrigerant flow based on evaporator outlet temperature and pressure conditions
• Maintains correct superheat levels for efficient and reliable system operation
• Helps protect the compressor by preventing liquid refrigerant carryover into the suction line
• Engineered for the demanding, 24/7 operating requirements of data center and server room environments
• Compatible with Liebert CRAC and precision air conditioning systems

The TXV is one of the most important components in any refrigeration circuit. By continuously modulating refrigerant flow in response to system load, it optimizes cooling capacity and energy efficiency while ensuring long-term equipment reliability. This genuine Liebert part is the recommended replacement to maintain system performance and preserve equipment warranties. Installation should be performed by a qualified HVAC/R technician.
