As the name implies, the electric ball valve is mainly composed of two parts, the upper part is the electric actuator, and the lower part is the valve. In the industrial process, the parameters used to control the flow and flow of various fluids (such as water, oil, chemical liquid, etc.) include temperature, pressure, flow, etc. Electric valve is a kind of independent valve widely used in recent years. It has stable reliability and multiple control functions. It meets the requirements of working conditions that most ordinary valves cannot use. It has become an indispensable control equipment in the process pipeline.

The electric ball valve has simple structure and long service life. It is applicable to almost all media, can greatly reduce the labor intensity of the operator, and is applicable to the position where the equipment cannot be manually operated or approached. It can complete remote operation of the valve, and the equipment height is not limited.

Type and classification of electric ball valve:
1. Electric valves are mainly divided into two categories according to different actuators. One is the angle travel, the other is the linear travel. The angle travel electric valve controls 90 degrees of rotation to reach both ends of the valve. The linear travel is used to realize the up and down movement of the valve plate, usually with equipment with a high degree of automation.

2. Functional switch type and regulating type, intelligent, explosion-proof, wherein the switch type is fully open and fully closed, and the regulating type controls all opening degrees, providing flow size adjustment function!

3. According to the form of valve position, it can be divided into ordinary electric ball valve, electric butterfly valve, electric control valve, solenoid valve, electric gate valve, electric stop valve, etc., which are applicable to many situations.

4. According to the shape of the valve, it can be divided into ordinary electric valve and micro electric valve.

Operating principle of electric ball valve:
The electric ball valve is connected with the valve by the electric actuator. After installation and commissioning, the valve is driven by the power supply to realize the opening and closing operation of the valve, so as to realize the purpose of opening and closing or adjusting the pipeline medium. The opening, closing and half opening state of the electric valve can be adjusted to control the flow of medium in the pipeline, but the solenoid valve does not meet this requirement.

The solenoid valve is a kind of electric valve. The magnetic field generated by the solenoid coil is used to pull the valve core, change the end of the valve body, turn off the power supply of the coil, and the valve core will return according to the pressure of the spring.

Electric ball valves are mainly used to block, distribute and change the flow direction of media in industrial control pipelines. It can only close its tightness through 90 degree rotation and small rotation torque. (John F. Kennedy, Rotary, Rotary, Rotary, Rotary, Rotary, Rotary, Rotary) Ball valves are suitable for on-off and globe valves, but recent development has designed ball valves for throttling and flow control purposes (such as V-type electric ball valves).

Use the electric actuator to drive the valve rod of the ball valve, and rotate the part of the valve to rotate the mechanical movement for 0-90 degrees. The rotating body of the ball valve is a sphere, and the circular through-hole or channel passes through the shaft.

characteristic:
The electric valve is usually connected with the valve by the electric actuator and becomes the electric valve after installation and commissioning. The electric valve is powered by electricity and connected with the electric actuator to drive the valve, so as to realize the valve opening and closing and regulating action. It can realize the purpose of switching or adjusting the pipeline medium.
