Phobya G1/4 Pressure Relief Valve

The Phobya 71142 is a brass pressure relief valve designed for custom water-cooling loops. It features a G1/4 thread with a short 4mm length and a low 16mm profile for versatile placement. An integrated O-ring seal ensures a secure connection at any installation point in the loop.

Builders with large loops facing high pressure

This valve suits enthusiasts running extensive cooling systems where extreme temperature swings create dangerous pressure spikes beyond standard reservoir capacity. It is not intended for basic loops where a standard reservoir adequately manages pressure differences without extra safety hardware.

Opens at 0.3-0.4 Bar release pressure

The valve activates between 0.3 and 0.4 Bar, equivalent to 4.3 to 5.7 psi, venting excess pressure before components risk damage. This specific trigger point is the critical specification determining whether the valve matches your system safety requirements.

FeaturesA pressure relief valve for even more safety in your system! In common systems usually a standard reservoir 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 for users with seriously large cooling loops the extreme temperature differences between operation and standby may cause such high pressures that it is advisable to release the pressure to avoid damages. This pressure relief valve can, for example, easily be screwed into a T-piece and therefore be installed at any point of the cooling

商品問答

How do I confirm the 71142 valve is releasing pressure at the rated 0.3-0.4 bar after installation?

The valve opens automatically when loop pressure reaches 0.3-0.4 bar (4.3-5.7 psi). You can verify function by observing coolant escape from the outlet during a deliberate over-pressure test or by noting that system pressure never exceeds the rated range during normal thermal cycling.

What comes with the 71142 valve and what extra fittings are required?

The package contains the brass pressure relief valve with a G1/4" thread, an integrated O-ring seal and a 16 mm low-profile body. You must supply a G1/4" T-piece, reservoir port or other female G1/4" fitting to mount it in the loop.

Which version of the Phobya pressure valve should I choose for a large custom loop?

The 71142 is the single model offered; it releases at 0.3-0.4 bar and fits any G1/4" port with its 4 mm thread length. Choose it when your loop volume and temperature swing create pressures that could exceed component ratings.
