Pressure Reducing Valve

Altecnic Ltd – Caleffi Group

PRESCAL® - SERIES 535 HIGH PERFORMANCE DIAL UP PRESSURE REDUCING VALVE

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 533H 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.

PRESCAL - SERIES 536 PRESSURE REDUCING VALVE

Pressure reducing valves are installed in 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 536 series is specially designed for hot and cold services in semicommercial or public buildings to equalise either the hot or cold supplies or both and prevent excessive pressure at water outlets such as taps, basins, toilets, dishwashers and other appliances.

SERIES 5360 - PRESSURE REDUCING VALVE FOR 1ST STAGE CONTROL
The 5360 pressure reducing valve is a high performance valve manufactured specifically for high rise buildings and other applications where high pressures are present and require staged pressure control. The 5360 pressure reducing valve carries out the first stage of pressure reduction in a two valve series where the pressure ratio between the inlet and outlet would be too high for a single pressure reducing valve to control.

SERIES 576 - DIRECT ACTING PRESSURE REDUCING VALVE
The model 576 reduces a higher inlet pressure to a lower downstream pressure, regardless of upstream pressure and flow variations. The simple and robust design allows stable operation, minimal maintenance as well as an assembly in various positions.

PRESCAL - SERIES 300 PRESSURE REDUCING VALVE
The prescal - series 300 is an automatic, pilot controlled, pressure reducing valve utilising the upstream and downstream pressures. The valve reduces the upstream pressure to a constant, predetermined downstream pressure regardless of fluctuations in upstream pressure and flowrate. Should the downstream pressure exceed the predetermined pressure, for example if the flow is isolated the valve closes automatically.
