Details
This pressure valve has a G1/4 external thread (OT, 5 mm long) and limits the pressure increase in a closed water cooling loop, one valve per pack. It is just 20.0 mm in height and 16.0 mm in diameter. Alphacool developed it for use in servers, workstations and industrial environments.

What it does
The valve is designed to manage pressure fluctuations in closed-loop water cooling systems. It safeguards individual components from excessive pressure build-up.
Size and installation
Thanks to its compact dimensions the valve is well-suited for installations where space is limited. Alphacool says 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.
Continuous use
Alphacool describes the valve as engineered to run in continuous use under demanding conditions. It features a durable housing that resists both thermal and mechanical stress. Alphacool also says the precision valve mechanism guarantees reliable performance throughout its entire operational lifespan.
What the loop needs
The valve screws into one free G1/4 port, and nothing else is needed for it. Other valves of this kind are in our pressure equalization fittings section.
