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 series is specially designed for cold services in houses or apartments to equalise the cold water supplies or both and prevent excessive pressure at outlets such as taps and showers.
533 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.
