Prescal Pressure Reducing Valve 15mm With Gauge Port (No Gauge) 533741H

Design

• • 533 pressure reducing valves have a specially shaped diaphragm to
  • give accurate pressure regulation in response to changes in
  • downstream pressure.
  • The larger outlet chamber creates a low exit velocity which is effective
  • in reducing water noise.
  • The control stem housing of the cartridge is made from a plastic
  • material with a low co-efficient of adhesion, which reduces the
  • probability of scale deposits forming, the main cause of pressure
  • reducing valve malfunction.
  • The cartridge and strainer screen are easily removed for periodic
    cleaning and maintenance.
  • Valves for use with copper tube have compression ends complying with BS EN 1254-2*
