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

The solenoid valve is a solenoid valve that generates a magnetic attraction to overcome the pressure of the spring to drive the spool action after the solenoid is energized; the electric valve drives the valve stem through a motor to drive the spool action, and the electric valve is divided into a shut-off valve and a regulating valve.

The difference between electric valve and solenoid valve:
The solenoid valve is a solenoid coil that generates a magnetic attraction to overcome the pressure of the spring to drive the spool to move after the solenoid is energized. Only a solenoid coil has a simple structure and a low price. It can only be switched.

The electric valve drives the valve stem through a motor to drive the spool to move. The electric valve is divided into (shut-off valve) and regulating valve. The shut-off valve is a two-position work that is fully open and fully closed. The regulating valve is equipped with an electric valve positioner, and the valve is dynamically stabilized in one position through closed-loop adjustment.
