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.
Note on application
Please use only in conjunction with clear transparent water cooling fluids. The particles and additives in Pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses. This may result in voiding the manufacturers warranty as well.
