Alphacool ES pressure valve G1/4’ OT

Description

The Alphacool ES Pressure Valve is designed to manage pressure fluctuations in closed-loop water cooling systems. Developed for use in servers, workstations, and industrial environments, it safeguards individual components from excessive pressure build-up.

Thanks to its compact dimensions—just 20.0 mm in height and 16.0 mm in diameter—the valve is well-suited for installations where space is limited. The G1/4″ thread ensures straightforward integration into existing cooling circuits. Installation is versatile, allowing the valve to be positioned where it most effectively contributes to system reliability.

Engineered for continuous use under demanding conditions, the valve features a durable housing that resists both thermal and mechanical stress. Its precision valve mechanism guarantees reliable performance throughout its entire operational lifespan.
