Electric gate Z941H 
 The electric gate is electric actuator control valve, in order to achieve the valve on and off. Can be divided into two parts, the upper part of the electric actuator, the lower half is divided into the valve. 
 Electric valve operation principle of the electric valve is usually connected by the electric actuator and valve, electric valve after installation and commissioning. The use of electric energy of electric valve connected to the electric actuator as a driving force to drive the valve, the valve switch, adjust the action. Switch or adjust the purpose to achieve the right media channels. 
 The solenoid valve is an electric valve types; magnetic field generated by electromagnetic coil to pull the spool, thus changing the body off the coil power, the spool will depend on the pressure of the spring return. 
 Use 
 Third, the use of electric valves: Electric valve: for liquid gas and wind system, the analog of the pipeline medium flow regulator is AI-controlled. Control valve and wind systems can also do two switches control the electric valve. 
 Electric valve: AI feedback signal can be controlled by the DO or AO, found in relatively large pipe and damper. 
 A switch in the form: 
 Electric valve drive of motor on or off action is completed to take some time to analog, you can do to adjust. 
 (2) the nature of work: 
 Electric valve drive motor, and more resistant to voltage surges. The solenoid valve is quick opening and quick off, is generally used in small flow and pressure requirements of the switching frequency electric valve contrary. The opening of the electric valve can control the state of open, off, half open, half shut, you can control the flow of media while the electromagnetic valve in the pipeline to reach this requirement
