PRESSURE REDUCER AND SUSTAINER WITH PLASTIC PILOTS (EN)

It is a valve controlled by a two-pilot system. One pilot maintains a constant upstream pressure and the other reduces the high pressure to a preset level. The valve gradually opens or closes to maintain the desired preset pressures.

FEATURES:

It does not need external energy, the energy is received from the water that circulates through the pipe.

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 two pilot valves. The sustaining pilot is set to maintain a constant minimum inlet pressure to the main valve. The reducing pilot is set in order to have a maximum outlet pressure downstream of the main valve. The valve opens partially to sustain inlet pressure and reduce outlet pressure. In the same way, it partially closes if the downstream pressure is higher than the predetermined one, or it opens if the pressure of the upstream pipe falls below the desired point.

APPLICATIONS:

The reducing sustaining hydraulic valve is used when a downstream pressure without oscillations is required, since it avoids pressure drops and overpressures.

It can be made in polyethylene tube and copper tube.
