Hydraulic Valve Manual Control Description The valve is controlled by manipulating a 3-way selection valve that opens or closes the flow of water, allowing the user easy control of it. -No external power, energy is received from the water flowing through the pipe. -Simplicity of design, construction and operation. The metal valve is an online hydraulic diaphragm valve with simple camera, with a basic operation of opening and closing due to the pressure of the existing water in the control chamber. The position of the main valve is controlled by manipulating 3 ways selection valve which opens or closes the flow of water through the main valve. Underground installed system, with a manual selection valve on the surface, for a comfortable handling of the valve. Electrovalve Description In a solenoid valve, the solenoid acts on the valve by an electrical signal, allowing open or close as needed.. The signal comes from a controller or other device remote control. There are two types: "Normally Open" and "Normally Closed". -Electric activation. -Fast activation. - Simply design, construction and operation. The valve is activated by line pressure and controlled by the solenoid. This solenoid opens or closes the passing flow through the valve by an electric pulse emitted by a controller, remote control or timer. In the normally open position, the solenoid allows the passage of fluid to the control chamber of the valve, allowing the filling thereof and throttling the flow passage through the valve. In the normally closed position, solenoid not allow the passage, so that the control chamber becomes empty, allowing the passage of fluid through the main valve.
