Technical Principle of Electric Valve

Electric valves are usually connected by electric actuators and valves and become electric valves after installation and debugging. The electric valve uses electric energy as power to connect the electric actuator to drive the valve, so as to realize the valve's switching and regulating action. So as to achieve the purpose of switching or regulating the pipeline medium.

Electric valves are usually driven by motors. It takes a certain amount of time to simulate the opening or closing of the valve, so it can be adjusted. Compare withstand voltage shock. Solenoid valves are fast-opening and fast-closing, generally used in small flow and pressure, requiring high switching frequency; electric valves on the contrary. The opening of the electric valve can be controlled. The state of the valve can be on, off, half on and half off. The flow rate of the medium in the pipeline can be controlled, but the solenoid valve can not meet this requirement.

Three-wire electric valve has three lines F/R/N, F represents forward action (or open action) control line, R represents reverse action (or close action) control line, N represents ground line. Solenoid valve is a kind of electric valve; it uses the magnetic field generated by the solenoid coil to pull the valve core, thereby changing the on-off of the valve body. When the coil is cut off, the valve core depends on the spring pressure to return.
