This model has been replaced with the D04FS. Click here for information.
The D04 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. The D04 is WRAS approved for use as a direct connection to the water main. For multi draw-off and commercial use, the D05 or D06 is recommended. Typically D04 valves are used to control water pressure on basin, sink or bath outlets.
