Designed for systems utilizing \u003cstrong\u003eR22 refrigerant\u003c\/strong\u003e, this component ensures meticulous flow regulation to the evaporator, maintaining an optimal \u003cstrong\u003esuperheat\u003c\/strong\u003e curve even under fluctuating heat loads. With its \u003cstrong\u003e5\/8\" x 5\/8\" ODF\u003c\/strong\u003e connections, the 180957P2S provides a secure, leak-proof fit essential for high-capacity light commercial and industrial HVACR cycles.\n\nAs a high-capacity \u003cstrong\u003e11-ton expansion valve\u003c\/strong\u003e, 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 \u003cstrong\u003eOEM Liebert part\u003c\/strong\u003e is the standard for technicians looking to restore factory-spec efficiency and reliability to aging R22 air-cooled systems.\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Refrigerant Metering:\u003c\/strong\u003e Optimized for 11-ton cooling loads to prevent evaporator flooding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eR22 System Compatibility:\u003c\/strong\u003e Specifically calibrated for the thermodynamic properties of R22 refrigerant.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust ODF Connections:\u003c\/strong\u003e Standard 5\/8\" x 5\/8\" solder connections for straightforward field installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced System Stability:\u003c\/strong\u003e Maintains target superheat to improve overall EER and equipment longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Reliability:\u003c\/strong\u003e Genuine Liebert component ensures perfect fit and function in precision cooling units.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the signs of a failing 180957P2S TXV?\u003c\/strong\u003e\u003cbr\u003e\nTechnicians 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this valve be used with R407C systems?\u003c\/strong\u003e\u003cbr\u003e\nWhile 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the superheat adjustable on this model?\u003c\/strong\u003e\u003cbr\u003e\nYes, this valve features an external adjustment nut, allowing technicians to fine-tune the superheat based on specific site conditions and load requirements.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
