Characteristics of electric ball valve
Electric flange ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used to regulate and control the fluid. It is similar to other valves. Than, it has the following advantages.
, the fluid resistance is small, and the ball valve has the smallest fluid resistance among all valves. Even the reduced diameter ball valve has a very small fluid resistance.
, the thrust bearing reduces the friction torque of the valve stem, making the valve stem's long-term operation balanced and flexible.
, the valve seat sealing performance is good, the sealing ring made of polytetrafluoroethylene and other materials is used, the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
, the valve stem seal is reliable. Since the valve stem only rotates and does not move up and down, the packing seal of the valve stem is not easily damaged, and the sealing capacity increases with the increase of the pressure of the medium.
Because materials such as polytetrafluoroethylene have good self-lubricating properties, the friction loss with the ball is small, which helps the ball valve have a long service life.
, the bottom-mounted valve stem and the convex steps on the valve stem head prevent the valve stem from spraying out. If the valve stem seal is damaged due to fire, metal contact can also be formed between the convex steps and the valve body to ensure the valve stem sealing.
If the ball valve is made of all stainless steel, the product is widely used in system control in the chemical, petroleum, textile, electric power, food and pharmaceutical, refrigeration, and paper industries.
