Descripción
The pressure-sustaining hydraulic solenoid valve is designed to maintain a minimum upstream pressure, regardless of changes in downstream flow or pressure. The open or closed position is controlled by the solenoid. It can be “Normally Open” or “Normally Closed”
The valve is regulated by a 2- or 3-way pilot, allowing full opening of the valve when the upstream pressure is greater than the preset pressure. If the pressure is lower, the valve will remain closed.
FEATURES:
- electrical activation.
- quick drive
- Simplicity in design, construction and operation.
- Stable and precise control regardless of flow rate.
You can choose any type of solenoid that we have available.
FUNCTION:
Pilot controlled by solenoid. This opens or closes the flow that passes through it thanks to an electrical impulse.
The pressure sustaining 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 upstream pressure, sending more or less pressure to the main valve control chamber.
If the upstream pressure falls below the one set in the pilot, the valve tends to throttle the flow of water or close, increasing the pressure up to the one set in the pilot. When the upstream pressure rises above the pilot setting, the valve will open, lowering the pilot setting pressure.
APP:
The pressure sustaining hydraulic solenoid valve is controlled automatically, by a programmer, performing the same function as the manual sustaining valve but at a remote distance.
It can be made in polyethylene tube and copper tube.
