Caleffi Pressure Reducers cutaway

Pre-adjustable pressure reducing valves with self-contained cartridge


Pressure reducing valves are devices which, when installed on private water systems, reduce and stabilise the pressure of the water entering from the public network. This inlet pressure, in general, is too high and variable to be applied directly to domestic systems. 

This series of pressure reducing valves have the feature to be preadjustable.

The pressure reducing valve can be set to the desired pressure value before installation, using an adjustment knob with a pressure setting indicator. After installation, the system pressure will automatically adjust itself to the set value.

The internal cartridge containing all the regulating components is pre-assembled as a “self-contained unit”, to facilitate inspection and maintenance procedures.
