Descripción
The hydraulic pressure reducing valve maintains a constant pressure downstream, regardless of changes in flow or pressure upstream. The valve is regulated by a 2 or 3-way pilot, allowing
a full opening of the valve when the downstream pressure is less than the desired pressure. The pilot has a regulator screw that allows the downstream pressure to be adjusted.
Characteristic:
- It does not need external energy, the energy is received from the water that circulates through the
pipeline. - Simplicity in design, construction and operation.
- Stable and precise control of the flow at the outlet.
Function:
- The pressure reducing valve is activated by line pressure and regulated by the pilot valve. This includes a diaphragm that controls the opening or closing of the main valve by downstream pressure, sending more or less pressure to the main valve control chamber.
- If the downstream pressure drops below the pilot setting, the valve will open by increasing the downstream pressure.
output previously set in the pilot. - When the downstream pressure rises above that set on the pilot, the valve tends to throttle the
passage of the water, reducing the pressure to that set on the pilot.
Applications:
The hydraulic pressure reducing valve is used when it is necessary that the downstream pressure does not exceed a preset pressure.
It can be made in polyethylene tube and copper tube.
For any assembly consult.
