Liebert 131852P1 Water Regulating Valve
For mission-critical cooling infrastructure, the Liebert 131852P1 Water Regulating Valve offers precise head pressure control by modulating flow based on refrigerant condensing pressure. This 1" 2-way water regulating valve (equivalent to Johnson Controls V46AL-1C) is a pressure-actuated, direct-acting component engineered for high-performance computer room air conditioning (CRAC) units. Designed to maintain stable refrigerant head pressure across various load conditions, it features an "all-range" 70 to 260 PSIG adjustment capability, making it compatible with most non-corrosive refrigerants. The 131852P1 is essential for chilled water systems and water-cooled condensers, ensuring efficient heat rejection in data center cooling environments. Its robust 2-way design utilizes a threaded NPT connection for secure integration into existing piping. By sensing the discharge pressure, this modulating valve optimizes water consumption and system efficiency, preventing overcooling while protecting the compressor from excessive head pressure during peak thermal loads.
Key Benefits- Broad Operating Range: Adjustable pressure setting from 70 to 260 PSIG provides versatile refrigerant pressure regulation.
- Precision Modulation: Maintains consistent condensing temperature by accurately throttling the water flow rate.
- Zero Hysteresis Design: Engineered without close-fitting sliding parts in the water passage to minimize water hammer and chatter.
- OEM Compatibility: Precision-fit Liebert replacement part ensures seamless integration with vertiv and Emerson cooling systems.
- Durability: Built for high-pressure water system applications up to 350 PSIG, featuring corrosion-resistant internal trim.
What is the primary function of the Liebert 131852P1 in a CRAC system?
This pressure-actuated valve senses high-side refrigerant pressure and adjusts the cooling water flow through the condenser to keep the system operating within the ideal pressure envelope.
Is this valve compatible with glycol solutions?
Yes, the Liebert 131852P1 is designed for use with both standard water and glycol-based heat transfer fluids typical in closed-loop HVACR systems.
How do I adjust the opening point of the valve?
The opening pressure setpoint can be field-adjusted using the range spring screw to match the specific head pressure requirements of your refrigerant type and ambient conditions.
