What is an electric valve? How much does it cost? Answered

Electric valves are usually connected to the valve by an electric actuator and become an electric valve after installation and commissioning. The electric valve is powered by electric energy and is connected to an electric actuator to drive the valve to realize valve switching and adjustment actions. In order to achieve the purpose of switching or adjusting the pipeline medium.

  Electric valves are usually connected to the valve by an electric actuator and become an electric valve after installation and commissioning. The electric valve is powered by electric energy and is connected to an electric actuator to drive the valve to realize valve switching and adjustment actions. In order to achieve the purpose of switching or adjusting the pipeline medium.

  The driving of electric valves is generally completed by a motor. The opening and closing action takes a certain amount of time to complete the simulation and can be adjusted. More resistant to voltage shock. The solenoid valve opens and closes quickly, and is generally used in situations with small flow and low pressure, requiring high switching frequency; the electric valve is reversed. The opening degree of the electric valve can be controlled, and the state is open, closed, half-open, and half-closed. It can control the flow of pipeline media, but the solenoid valve cannot meet this requirement.

 

  The three-wire electric valve has three circuits: F/R/N. F is the forward action (or opening action) control line, R is the reverse action (or closing action) control line, and N is the grounding wire. The solenoid valve is a solenoid valve that uses the magnetic field generated by the solenoid coil to pull the valve core, thereby changing the closing method of the valve body, turning off the coil power, and the valve core returns by the pressure of the spring.

  The valve electrical device is an indispensable device for realizing valve program control, automatic control and remote control. Its movement process can be controlled by stroke, torque or axial thrust.

  The characteristics and utilization of self-operating valve actuators depend on the type of valve, the operating specifications of the equipment and the location of the valve on the pipeline or equipment. The correct selection of the valve actuator is crucial to prevent overloading (operating torque higher than control torque). The price is about 3,000 yuan. Of course, the most important thing is quality. What do you think? In addition, Shanghai Longmeng valves are cost-effective. You will be satisfied.
