D04FS Pressure Reducing Valve

The D04FS pressure reducing valve is designed to protect household appliances against excessive supply pressures. By installing a pressure reducing valve, water consumption can be drastically reduced; water flow noise and over-pressurisation damage is avoided. For multi draw-off and commercial use, the D05 or D06 is recommended.


Typically D04FS valves are used to control water pressure on basin, sink or bath outlets. The D04FS has been awarded the Waterwise Marque.
