Hydraulic control

Pressure reducer:

Function: Reduces and maintains constant the pressure downstream of the valve, determined in the pilot setting.

Pressure sustainer / Relief:

Function: The valve is kept closed while the upstream pressure does not reach the pressure determined in the pilot setting. Relief: The hydraulic valve remains closed with an upstream pressure lower than the setting of the pilot holder; The valve opens when the upstream pressure exceeds the set pressure, relieving excess pressure.

Pressure reducer-sustainer:

Function: The valve is kept closed as long as the upstream pressure does not reach the pressure determined in the setting of the sustaining pilot. When the valve opens, the downstream pressure determined in the setting of the reducing pilot will be reduced and kept constant.

Flow limiter:

Function: It allows to limit a predetermined flow, as it passes through the valve, using the water pressure itself in the conduction, regardless of the variations in pressure or flow demanded.

Flow limiter - pressure reducer:

Function: It allows to limit a flow through the hydraulic valve, depending on the setting of the differential pilot, proportional to the loss of load created in the orifice plate or to reduce the pressure downstream of the valve constantly, according to the setting of the regulating pilot.
