    The difference between electric valve and solenoid valve


    The solenoid valve is magnetically attracted after the electromagnetic coil is energized to overcome the pressure of the spring to drive the spool. The electromagnetic coil has a simple structure and is cheap, and can only realize the switch. The electric valve drives the valve stem through the motor to drive the spool movement.The valve is divided (closed valve) and regulating valve.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.Switch form: The solenoid valve is driven by the coil and can only be turned on or off. The switching time is short.

    The drive of the electric valve is generally a motor, and the opening or closing action requires a certain amount of time to simulate, and can be adjusted.2. Nature of work: Solenoid valves generally have a small flow coefficient and a small difference in working pressure.The solenoid valve is fast open and fast closed. It is generally used in small flow and small pressure, and the electric switch is required in the place where the switching frequency is large.The opening of the electric valve can be controlled. The state has open, closed, half open and half closed, which can control the flow of the medium in the pipeline and the solenoid valve can not meet this requirement.
