Series BPR1/2 Calibrated Pressure Relief Valves
are spring operated bronze relief valves designed to be used only as protection from the build up of excessive pressure in systems containing water, oil or air.
It is not an ASME approved safety relief valve and should not be used in system applications with this requirement. This also incorporates a calibrated adjustment feature for setting the valve to the relief pressure required.
To set relief pressure, rotate adjustment cap clockwise until seated.
Pressurize sprinkler system to the pressure that you wish to provide relief.
Once system pressure has been set slowly turn pressure relief valve adjustment cap counter-clockwise until
the valve outlet starts to bleed off pressure.
Once the valve starts to “spit” then slowly close the valve cap until the valve stops “bleeding off” pressure.
Check the system pressure gauge to make sure pressure is maintained at the relief pressure.
Repeat steps until proper relief pressure has been set.
Make sure to test setting by pressurizing system above relief setting to verify proper relief valve function.
Use an appropriate thread sealant to prevent leakage of the threaded connections.
Refer to Authority Having Jurisdiction or NFPA13 for proper installation location in the sprinkler system
