533H pressure reducing valves have a specially shaped diaphragm to give accurate pressure regulation in response to changes in
downstream pressure.
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.
The 533H series of pressure reducing valve is certified according to BS EN 1567 for operating with inlet water temperatures up to
80˚C.
The 533H is specifically designed for higher flow rates with low a low noise level when operating.
