What it is

The 5 Bar PRV (Brass Body) Loose Nut 3/4" is a pressure relief valve for cylinder installations, listed under the Miscellaneous Cylinder Spares range. It discharges excess pressure at its 5 bar set point to protect the cylinder and its associated components. The valve has a brass body and a 3/4" loose nut connection.

Signs this part needs replacing

  • Water discharging continuously from the tundish or relief outlet
  • The valve weeping or dripping with the system at normal pressure
  • System pressure rising above the valve's 5 bar set point
  • The valve failing to reseat after it has opened
  • Scale or debris causing the valve to stick or pass water

Before you order

  • Confirm the required set pressure is 5 bar for the installation
  • Confirm the connection size is 3/4" and the loose nut arrangement suits the existing pipework
  • Check the existing valve's body and connection type before ordering
