Electric valve is usually connected by the electric actuator and the valve, after installation and commissioning to become electric valve. Electric valve using electric power as power to turn on the electric actuator to drive the valve, to achieve the valve switch, adjust the action. So as to achieve the switch on the pipeline or the purpose of regulation.
Electric valve drive is generally used to motor, open or close the action to complete the need for a certain amount of time analog, you can do regulation. More resistant to voltage shocks. Solenoid valve is quick and fast off, generally used in small flow and small pressure, requiring a large frequency of switching; electric valve on the contrary. Electric valve valve opening can be controlled, the state has open, closed, half open half, you can control the flow of media in the pipeline and the solenoid valve does not meet this requirement.
Three-wire electric valve with F / R / N three lines, F on behalf of the positive action (or open action) control line, R on behalf of the reverse action (or close action) control line, N on behalf of the ground. Solenoid valve is a type of electric valve; is the use of electromagnetic field generated by the electromagnetic coil to pull the valve core, thus changing the valve body off, the coil power, spool on the spring pressure to return.
