Control valve - Import export

The valve controls tanks and reservoirs emptying and avoids overflow. The valve operates by means of a differential hydraulic float complete with regulating levels mounted on the tank side. The float maintains the valve closed and opens only when the minimum pre-set level is reached. Once the valve is open, float allows tank inlet until maximum water level is reached again.

The valve controls downstream flow to a pre-set and constant value in order to limit water consumptions and preserve pipeline fill rate or to set a maximum demand value. The valve is controlled by a differential hydraulic pilot that senses the pressure fall generated by water flow into a calibrated orifice.

This valve controls water level in high level reservoirs to avoid overflow, without any external control system like float control etc. The valve remains completely open until the closing input is transmitted by the 3-ways piezometric altitude pilot.

The valve closes totally the pipe line when back flow occurs. The valve is complete with an hydraulic control circuit able to regulate operation’s speed during closing, preventing surge.

The valve isolates pumps from the system during pumps starting and stopping to protect pipe lines and pumps itself. The valve is equipped with a control solenoid valve that is switched on at pump starting and is able to fulfill pipe line gradually, reducing pressure rising peaks and allowing soft starting of the pump with closed outlet. The valve controls pump stopping as well, gradually closing before sending a closing signal to the pump. In case of casual pump stop, the valve acts also as an automatic check valve, preventing backflow over the impeller.
