Visible Pre-adjustable Pressure Reducing Valves
Visible Pre-adjustable Pressure Reducing Valves
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 features visual pre-adjustment, which means that the desired pressure is set by the visual adjustment handwheel before the installation. After installation, the system pressure is automatically maintained at the set value.

Construction details
The pressure reducing valves are fitted with an operating knob and a pressure setting indicator which is visible on both sides. This pressure indicator features incremental step operation, The system pressure can therefore be pre-set to the desired value, even before the pressure reducing valve is installed.
