What it is

The 4 Bar PRV 1/2" M x 15mm is a pressure reducing valve manufactured by Popular Cylinder for its cylinder spares range. It sits within the Popular Cylinder Spares cold water inlet controls group, where it regulates the incoming supply pressure to the cylinder. The valve is set to 4 bar and carries a 1/2" male connection and a 15mm connection.

Signs this part needs replacing

  • Outlet pressure noticeably above or below the 4 bar setting
  • Water weeping from the valve body or its connections
  • Reduced or inconsistent flow through the cold water inlet controls
  • Knocking, humming or vibration when taps are opened or closed

Before you order

  • Confirm the cylinder is a Popular Cylinder unit and the valve sits in the cold water inlet controls group
  • Check the existing valve connections match 1/2" male and 15mm
  • Confirm the required pressure setting is 4 bar
