What it is

The Dial Up Adjustable 1.5-6 Bar PRV 315i is a pressure reducing valve with a 1 1/4 MBSP union connection, produced by Popular Cylinder Spares as part of its cold water inlet controls range. It regulates incoming cold water pressure to the cylinder and allows the outlet setting to be adjusted on site between 1.5 and 6 bar. The dial-up mechanism is used to set and change the outlet pressure to suit the installation.

Signs this part needs replacing

  • Outlet pressure cannot be held at the set value or drifts after adjustment
  • Downstream pressure reads outside the expected range on a gauge
  • Water continues to pass through the valve when all outlets are closed
  • Leaks from the union connection or the valve body
  • Adjustment becomes stiff, erratic or unresponsive

Before you order

  • Confirm the existing valve is a 315i model
  • Check the connection is 1 1/4 MBSP union
  • Confirm the required outlet pressure falls within the 1.5-6 bar range
  • Verify the cylinder is a Popular Cylinder with cold water inlet controls
