Details
The Alphacool Eiszapfen Pressure Valve G1/4 - Chrome is a pressure relief valve with a G1/4 thread for a water cooling loop, one valve per pack. It releases at a pressure of 0.3-0.4 kg/cm² at 4.3-5.7 psi. Alphacool lists it as the Eiszapfen pressure relief valve.

When a loop needs one
Alphacool calls it a valve for even more safety in your system. In common systems a standard reservoir usually suffices to level the occurring pressure differences. Also, the parts installed in a system are usually pressure-tested up to at least 2 bar. But users with seriously large cooling loops see extreme temperature differences between operation and standby. These may cause such high pressures that it is advisable to release the pressure to avoid damages.
Where it goes
The valve can, for example, easily be screwed into a T-piece from our splitter fittings and therefore be installed at any point of the cooling loop. Some reservoirs also offer additional openings, which are usually equipped with plug caps, and the valve installs just as easily at these threads. Due to the G1/4 thread size and the short thread length of only 4 mm, it can be used in just about any spot of the watercooling system. The low profile of only 16 mm without the thread also makes it very versatile. An O-ring seal at the thread gives added security for your system.
Notes
- Alphacool's note on application: use only clear, transparent water cooling fluids. The particles and additives in pastel liquids can clog and permanently damage radiators, pumps, coolers and hoses.
