Pressure Relief Valves maintain a low differential pressure and reduce the risk of injury in systems that incorporate internal components which off-gas or other sources of pressure buildup that can create a dangerous high internal pressure situations. PREVCO offers a single poppet and a dual poppet version for high reliability. Both incorporate our dual seal technology. Pressure Relief Valves fit in Standard #4 SAE Port* (Same as PREVCO Dual Seal Vent Plug)

You might also be interested in our Debris Blocker which is designed as a sticker, featuring a finely woven Stainless Steel filter, which is affixed to the interior of the endcap opposite the PRV.  Should the valve activate, the filter serves to eliminate any dirt or particles that might otherwise flow through the valve and potentially lead to its failure.  While these are optional, at a cost of $10.00 each, it could be an additional safety feature you might consider?  https://prevco.com/shop/pressure-relief-valves/debris-blocker-for-prv/
