Altecnic - Caleffi 2 inch High Temp Pressure Reducing Valve with Gauge

Altecnic - Caleffi Prescal 535H pressure reducing valves when installed on water systems reduce and stabilise the pressure entering from the public mains. This incoming pressure is generally too high and variable for direct application to domestic systems.

535H 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 535H series of pressure reducing valve is certified according to BS EN 1567 for operating with inlet water temperatures up to 80 deg C.

The 533H is specifically designed for higher flow rates with a low noise level when operating.
