What it is

The Altecnic Prescal is an adjustable pressure reducing valve used on cold water inlet controls for cylinder installations. It regulates incoming mains pressure to a set outlet value between 1 and 6 bar, protecting downstream pipework, fittings and cylinder components. This version has 28mm connections and a gauge port.

Signs this part needs replacing

  • Outlet pressure at taps higher or lower than the set value
  • Pressure gauge reading drifting, or the valve failing to hold a setting
  • Reduced or unstable flow at outlets fed from the cylinder
  • Noise, chatter or water hammer in the pipework on draw-off
  • Weeping or visible leaks from the valve body or gauge port

Before you order

  • Confirm the pipework at the valve position is 28mm
  • Check the required outlet pressure setting falls within the 1-6 bar range
  • Verify the valve is fitted to the cold water inlet control on the installation
  • Check whether a gauge port connection is required at that point
