Grey PRV - 6.9bar (100psi)
Pressure relief valve for Cornelius style kegs, MK 4 Kegland Regulators and kegmenter lids. Grey PRV's will open at approximately 6.9 bar and act as a safety mechanism is systems using pressurised gas.
As a safety precaution please make sure PRV's are clean and free of sugar to prevent the spring getting stuck and allowing a higher than stated pressure to build up.
We recommend replacing your PRV every 2 years, or more frequently in situations with continued use as the spring tension can deteriorate over time and cause the PRV to open at lower pressures than stated.
Please be aware these pressure relief valves may not be compatible with older kegs or older Italian Style Corny kegs.
