The electric valve is usually connected by an electric actuator and a valve, and is installed as an electric valve. The electric valve uses electric energy as power to turn on the electric actuator to drive the valve to realize the switching and regulating action of the valve. Thereby achieving the switching or regulating purpose of the pipeline medium.
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. Compare withstand voltage shock. The solenoid valve is fast open and fast closed, generally used in small flow and small pressure, where the switching frequency is required; the electric valve is reversed. 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. The three-wire electric valve has three lines of F/R/N, F stands for forward action (or open action) control line, R stands for reverse action (or close action) control line, and N stands for ground line. The solenoid valve is a kind of electric valve; the magnetic field generated by the electromagnetic coil is used to pull the valve core, thereby changing the opening and closing of the valve body, the coil is de-energized, and the valve core is returned by the pressure of the spring.
