Mares XR Over Pressure Relief Valve

1 item left

The Mares XR Over Pressure Relief Valve fits into one of the low pressure ports of your first stage and acts as a fail safe against free flows 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 13bar (+/- 0.5 bar).

  • Standard LP port thread, 3/8 UNF
  • Set to 13bar, nominally, with +/-0.5bar tolerance
  • Chrome plated brass
  • Standard regulator spring
