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

The Classic TRV is top of its class for design, performance, quality and reliability. Its classical looks and unobtrusive design make it suitable for any heating installation. An integrated radiator balancing insert retains the radiator balancing setting when the TRV and lock shield valves are closed for cleaning, decorating etc. The valve can be mounted vertically or horizontally at either end of a radiator. To work correctly, the Valencia Classic TRV should be installed to a two pipe heating system and also have a free flow of air around the head to sense temperature.
