D05F PRV 1/2" to 1"

The D05F pressure reducing valve is designed to protect household water installations against excessive pressure from the supply.


They can also be used for industrial or commercial applications within the range of their specification. By installing a pressure reducing valve, pressurisation damage is avoided and water consumption is reduced. The set pressure is also maintained constant, even when there is wide inlet pressure fluctuation. Reduction of the operating pressure and maintaining it at a constant level minimizes flow noise in the installation. The D05 is for use as a direct connection to the water main.


For commercial and/or industrial use, the D06 is recommended. Typically, these valves are used to control water pressure on the inlets to unvented hot water cylinders and cold services. The D05F has been awarded the Waterwise Marque.
