Adjustable Pressure Relief Valve with Gauge (0-15psi) With Corny Keg Gas Ball Lock
This Ball Lock Adjustable Pressure Valve with Gauge allows you to relieve pressure while transferring your beer from one keg to another.
It makes for a "closed" transfer system. You can also naturally carbonate your beer and pressure ferment in a keg without having to worry about over carbonating. Simply set the desired pressure with the adjustable valve.
The farthest end away from the ball lock disconnect is how you adjust the pressure. Simply turn the valve until the desired pressure reached. It will maintain it from there. The gauge reads 0-15 psi.
