Overview

  • 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
