Caleffi Altecnic 533 3/4 in Pressure Reducing Valve No Gauge 533051

The 533 series is specially designed for hot and cold services in houses or apartments to equalise the hot or cold water supplies or both and prevent excessive pressure at outlets such as taps and showers. They 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. High flow rate Low operational noise Can be used in semi-commercial applications Screwed iron connection Type: F x F
