{"product_id":"liebert-131852p1","title":"Liebert 131852P1 Water Regulating Valve","description":"\u003cp\u003eFor mission-critical cooling infrastructure, the \u003cstrong\u003eLiebert 131852P1 Water Regulating Valve\u003c\/strong\u003e offers precise \u003cstrong\u003ehead pressure control\u003c\/strong\u003e by modulating flow based on \u003cstrong\u003erefrigerant condensing pressure\u003c\/strong\u003e. This \u003cstrong\u003e1\" 2-way water regulating valve\u003c\/strong\u003e (equivalent to Johnson Controls V46AL-1C) is a pressure-actuated, direct-acting component engineered for high-performance \u003cstrong\u003ecomputer room air conditioning (CRAC)\u003c\/strong\u003e units. Designed to maintain stable \u003cstrong\u003erefrigerant head pressure\u003c\/strong\u003e across various load conditions, it features an \"all-range\" \u003cstrong\u003e70 to 260 PSIG\u003c\/strong\u003e adjustment capability, making it compatible with most \u003cstrong\u003enon-corrosive refrigerants\u003c\/strong\u003e. The 131852P1 is essential for \u003cstrong\u003echilled water systems\u003c\/strong\u003e and \u003cstrong\u003ewater-cooled condensers\u003c\/strong\u003e, ensuring efficient heat rejection in \u003cstrong\u003edata center cooling\u003c\/strong\u003e environments. Its robust 2-way design utilizes a \u003cstrong\u003ethreaded NPT connection\u003c\/strong\u003e for secure integration into existing piping. By sensing the discharge pressure, this \u003cstrong\u003emodulating valve\u003c\/strong\u003e optimizes water consumption and system efficiency, preventing overcooling while protecting the compressor from excessive head pressure during peak thermal loads.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Operating Range:\u003c\/strong\u003e Adjustable pressure setting from \u003cstrong\u003e70 to 260 PSIG\u003c\/strong\u003e provides versatile \u003cstrong\u003erefrigerant pressure regulation\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Modulation:\u003c\/strong\u003e Maintains consistent \u003cstrong\u003econdensing temperature\u003c\/strong\u003e by accurately throttling the \u003cstrong\u003ewater flow rate\u003c\/strong\u003e.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZero Hysteresis Design:\u003c\/strong\u003e Engineered without close-fitting sliding parts in the water passage to minimize \u003cstrong\u003ewater hammer\u003c\/strong\u003e and chatter.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOEM Compatibility:\u003c\/strong\u003e Precision-fit \u003cstrong\u003eLiebert replacement part\u003c\/strong\u003e ensures seamless integration with \u003cstrong\u003evertiv\u003c\/strong\u003e and \u003cstrong\u003eEmerson\u003c\/strong\u003e cooling systems.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e Built for \u003cstrong\u003ehigh-pressure water system\u003c\/strong\u003e applications up to 350 PSIG, featuring corrosion-resistant internal trim.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary function of the Liebert 131852P1 in a CRAC system?\u003c\/strong\u003e\u003cbr\u003e\nThis \u003cstrong\u003epressure-actuated valve\u003c\/strong\u003e senses high-side refrigerant pressure and adjusts the cooling water flow through the condenser to keep the system operating within the ideal pressure envelope.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this valve compatible with glycol solutions?\u003c\/strong\u003e\u003cbr\u003e\nYes, the \u003cstrong\u003eLiebert 131852P1\u003c\/strong\u003e is designed for use with both standard water and \u003cstrong\u003eglycol-based heat transfer fluids\u003c\/strong\u003e typical in closed-loop HVACR systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I adjust the opening point of the valve?\u003c\/strong\u003e\u003cbr\u003e\nThe \u003cstrong\u003eopening pressure setpoint\u003c\/strong\u003e can be field-adjusted using the range spring screw to match the specific \u003cstrong\u003ehead pressure requirements\u003c\/strong\u003e of your refrigerant type and ambient conditions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong style=\"color: red;\"\u003eThis item is not eligible for free shipping.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
