The 520 adjustable thermostatic mixing valves is designed to maintain the preset temperature of the mixed water delivered to the user despite variations in the temperature of the water contained in the system.

The 520 is ideally suitable of use on underfloor heating to maintain the circulating water through the underfloor coil at the preset temperature, by mixing hot water from the boiler with the return water from the coil.

Pressure reducing valves are installed in residential water systems to reduce and stabilise inlet pressures from mains water supplies or boosted water systems, which generally are too high and variable for domestic appliances to function correctly.
The 533 Cold series is specially designed for cold services in houses or apartments to reduce or equalise the cold water supply and prevent excessive pressure at outlets such as taps and showers.

The series 536 range of pressure reducing valves is designed for semi-commercial and industrial applications.

The series 535 range of dial up pressure reducing valves is designed for semi-commercial and industrial applications.
