Applications
The pressure reducer valve is used in places where pressure is needed for:
The pilot acts on the valve so that it has a modulating function, in order to keep the downstream pressure constant for the setting value.
Functioning
The pilot sets the downstream pressure regardless the inlet pressure. If the outlet pressure is lower than the preset pressure the pilot will open the valve and it will act just when the outlet pressure exceeds the preset one.
The reducer pilot must be adjusted regarding the installation needs. Turning the pilot screw clockwise you will reduce the outlet pressure. Turing the pilot anti-clockwise you will increase the outlet pressure.
