Standard pattern pressure reducing valve, D05FS
 |
| Pressure reducing valves of this type 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.. |
