The electromagnetic valveAfter the solenoid coil is energized, it produces magnetic attraction and overcomes the pressure of the spring to drive the valve core to move; the electric valve drives the valve stem through the motor to drive the valve core to moveElectric valveIt is divided into shut-off valve and regulating valve.
The difference between electric valve and solenoid valve:
The electromagnetic valveAfter the solenoid coil is energized, it produces magnetic attraction and overcomes the pressure of the spring to drive the spool to move. It is a solenoid coil with simple structure and low price, which can only be switched;
Electric valveThe valve stem is driven by an electric 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.
The purpose of electric valve and solenoid valve:
The electromagnetic valve: Used for on-off control of liquid and gas pipelines, two-position DO control.Generally used for the control of small pipelines.
Electric valve: It is used to adjust the analog quantity of the pipe medium flow of liquid, gas and wind system, which is AI control.In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
