What it is

The 315I is an adjustable pressure reducing valve for cylinder installations, listed in the Miscellaneous Cylinder Spares range. It regulates incoming supply pressure down to a set outlet pressure between 1.5 and 6 bar, protecting the cylinder, pipework and outlets downstream. The valve is fitted with a 1/2 in MBSP union connection.

Signs this part needs replacing

  • Outlet pressure drifts or will not hold the set value
  • Downstream pressure stays high or fluctuates regardless of adjustment
  • Water weeping from the valve body, bonnet or adjustment assembly
  • Scale or debris build-up affecting regulation
  • Hammering or noise through the pipework at the valve

Before you order

  • Confirm the incoming supply pressure falls within the 1.5 to 6 bar adjustment range the installation needs
  • Check the connection is 1/2 in MBSP union and that the existing pipework matches
  • Confirm the reference 315I matches the valve being replaced
  • Check there is clearance around the valve for adjustment and future service access
