Liebert 180957P2S TXV Valve

The Liebert 180957P2S is a heavy-duty, 11-ton thermostatic expansion valve (TXV) engineered for precision cooling applications, particularly within Liebert and Vertiv environmental control units. Designed for systems utilizing R22 refrigerant, this component ensures meticulous flow regulation to the evaporator, maintaining an optimal superheat curve even under fluctuating heat loads. With its 5/8" x 5/8" ODF connections, the 180957P2S provides a secure, leak-proof fit essential for high-capacity light commercial and industrial HVACR cycles. As a high-capacity 11-ton expansion valve, it is built to handle the rigorous demands of data centers and technology-dependent facilities where temperature stability is non-negotiable. The balanced port design helps neutralize the effect of pressure drops, preventing hunting and ensuring the compressor remains protected from liquid slugging. This OEM Liebert part is the standard for technicians looking to restore factory-spec efficiency and reliability to aging R22 air-cooled systems. Key Benefits

Common Questions

What are the signs of a failing 180957P2S TXV?
Technicians typically observe "hunting" where suction pressure fluctuates wildly, or find the evaporator frozen due to a valve stuck open. High superheat or low suction pressure often indicates the valve is restricted or stuck closed.

Can this valve be used with R407C systems?
While the 180957P2S is primarily labeled for R22 in many legacy catalogs, always verify the specific power assembly charge. Using a valve with the incorrect refrigerant charge will result in poor superheat control and potential compressor damage.

Is the superheat adjustable on this model?
Yes, this valve features an external adjustment nut, allowing technicians to fine-tune the superheat based on specific site conditions and load requirements.
