Over Pressure Relief Valve fits into one of the low pressure ports of your first stage and acts as a fail safe, caused by excessive intermediate pressure and intermediate pressure creep that can occur in a malfunctioning first stage or a first stage that requires a service.
Rather than the excess pressure being forced out of a second stage which could cause a free flow, the over pressure relief valve will be forced open at 11.7bar (+/- 0.5 bar).
Features
- Standard LP port thread, 3/8 UNF
- Set to 11.7bar, nominally, with +/-0.5bar tolerance
- Chrome plated brass
