This pull style PRV for your Cornelius (NC) type keg lid has a lower release pressure rating than the ones commonly found on a keg lid. It is rated to release at 4.5 Bar with a 10% tolerance. It can be used to help protect your spunding valve with the integrated 0-4 bar gauge.
Please be aware that these pressure relief valves should be clean to work correctly. If dried up beer or sugar gets into the pressure relief valve then clean this out immediately as this can effect the safe working and opening pressures.
This is a safety device only and may NOT be used as a spunding valve!
A suitable spunding valve can be found in our shop.
