The fluid resistance of the electric ball valve is very small.

The electric ball valve is one of the smallest fluid resistances in all valve classifications. Even the reduced diameter pneumatic ball valve has a fluid resistance. The thrust bearing reduces the valve stem friction torque, which makes the valve stem smooth and flexible for long-term operation. Good sealing performance, sealing ring made of elastic material such as PTFE, the structure is easy to seal, and the valve sealing capacity of the electric ball valve increases with the increase of the medium pressure; the valve stem seal is reliable, because the valve stem is only imitation Rotating and transporting without lifting movement, the packing seal of the valve stem is not easy to break, and the sealing capacity increases as the pressure of the medium increases; since the material such as PTFE has good self-lubricating property, the friction loss with the sphere is small, Therefore, the electric ball valve has a long service life; anti-static function: a spring is arranged between the ball, the valve stem and the valve body, and the static electricity generated by the switching process can be derived; the bottom mounted valve stem and the stem of the valve stem are prevented from being sprayed by the valve stem. If the valve stem seal is broken due to fire, metal contact can be formed between the convex step and the valve body to ensure the valve stem is sealed.
 

  The electric ball valve is composed of a ball valve with a pneumatic actuator. The pneumatic actuator is divided into a double-acting pneumatic actuator and a single-acting pneumatic actuator. The solenoid valve is controlled to realize the ball valve switching action. The electric ball valve can realize intelligent control, quickly open or close the pipeline, and can effectively control and manage the pipe network.
