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
