The Automatic Control Valve is a hydraulically operated valve designed to open, close and regulate flow automatically using the pressure of the pipeline itself, without the need for external energy sources such as electricity or compressed air.

The operating force is generated by the diaphragm or piston actuator, whose effective surface area is larger than that of the valve disc. This differential area creates the required force to control the valve opening. The opening and closing behavior of the valve is precisely regulated by pilot valves, which adjust the pressure acting on the actuator chamber.

Thanks to its reliable hydraulic control principle, the automatic control valve is widely used in water distribution networks, pumping stations and industrial applications where stable pressure and flow control are required. The robust design ensures long service life, high operational reliability and precise control under varying pressure conditions.

Different control functions such as pressure reducing, pressure sustaining, pressure relief, flow control and level control can be achieved by selecting the appropriate pilot configuration.
