Solenoid valve is a solenoid Coil magnetic appeal to overcome the spring pressure valve core, an electromagnetic coil, the structure is simple, cheap, and just switch;
Power is driven by the motor of the valve stem and valve core, electric valves (shutoff valve) and the control valve. Shutoff valves are two-work that is fully open and fully closed, control valve is mounted above the electric valve positioner, through dynamic stability of closed-loop regulation to keep the valve in one position.
Drive through the solenoid valve coil can only be on or off, switch when time is short.
Electric valve drives are generally used motor, open/close action takes some time to complete analog, you can adjust.
