What is the difference between the solenoid valve coil and the electric valve coil?

The solenoid valve is magnetically attracted by the electromagnetic coil to overcome the pressure of the spring to drive the spool, and the electromagnetic coil has a simple structure and a low price, and can only realize the switch;
The electric valve drives the valve stem through the motor to drive the spool, and the electric valve is divided into (shut-off valve) and regulating valve. The shut-off valve is a two-position operation that is fully open and fully closed. The regulating valve is equipped with an electric valve positioner on the above, and the valve is dynamically stabilized in one position by closed loop adjustment.

The use of electric and solenoid valves:
Solenoid valve: Switch control for liquid and gas lines, is a two-DO control. Generally used for the control of small pipes.
Electric valve: Analog adjustment for pipe media flow in liquid, gas and wind systems, is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
