Products Description

The working principle of an electric ball valve is to operate the valve by adjusting the current through an electric actuator. An electric ball valve consists of an electric actuator and a ball valve. The plug body is a spherical body with the ability to rotate 90 degrees. The input and output signals of the electric actuator of the electric ball valve are 4-20mA and the standard signal of the 220VAC power supply. The motor unit drives the gear turbine worm angle torque to control the opening and closing of the ball valve, distribute and change the flow direction of the medium, or adjust the proportional degree of the valve core rotation, that is, the valve opening is proportional to the control fluid.

Product characteristics

1.Easy to assemble: The installation process of electric valves is relatively simple, without the need for complex piping, solenoid valves, compressors, and other supporting equipment.

2.Low failure rate: Due to the use of motor-driven mode, the electric ball valve operates more smoothly during the opening and closing process, reducing the occurrence of excessive instantaneous impact and thus lowering the failure rate.

3.Low fluid resistance: Ball valves have the lowest fluid resistance among all valve types, even for reduced diameter ball valves, their fluid resistance is quite small.

4.Quick and convenient switch: simply rotate the valve stem 90 °, and the ball valve can complete the fully open or fully closed action, achieving fast opening and closing.

5.Good sealing performance: The sealing ring of the ball valve seat is generally made of elastic materials such as polytetrafluoroethylene, which is easy to ensure sealing, and the sealing force of the ball valve will increase with the increase of medium pressure.

6.Reliable stem sealing: When the ball valve is opened and closed, the stem only rotates, so the packing seal of the stem is not easily damaged, and the sealing force of the stem reverse seal will also increase with the increase of medium pressure.

7.Compact structure and light weight: The structural design of the electric ball valve makes it small in size and lightweight among valves with the same function, making it easy to maintain and transport.
