The detailed information
Structural Features

1. There is a locking hole in the fully open and fully closed position of the valve to prevent misoperation by non-workers.

2. Set the step at the lower part of the valve stem so that the valve internal pressure does not rise abnormally and the valve stem is released.

3. A refractory sealing ring is arranged between the ball and the valve seat, and the valve seat still has a sealing effect after being burnt.

4, the switch is fast, flexible opening and closing, long life, safe and reliable.

5. Pneumatic and electric ball valves can be centrally controlled from a distance, and can meet the needs of computer program control.

Main Features

1. The thrust bearing reduces the frictional torque of the valve stem, which makes the valve stem smooth and flexible for long-term operation.

2. 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.

3. Since the material such as polytetrafluoroethylene has good self-lubricating property and the friction loss with the spherical body is small, the service life of the ball valve is long.

4. The bottom mounted valve stem and the stem of the valve stem prevent the valve stem from being sprayed out. 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.

5, the fluid resistance is small, the ball valve is the smallest of the fluid resistance of all valves, even the diameter of the ball valve, its fluid resistance is quite small.

6. The sealing performance of the valve seat is good. The sealing ring made of elastic material such as PTFE is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.

7. The valve stem seal is reliable. Because the valve stem only rotates and moves 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.

Applications

Electric ball valve accounts have been widely used in petroleum, natural gas, medicine, food, hydropower, nuclear power, electric power, water supply and drainage, heating, metallurgy and other industries, and are vital mechanical products for national defense construction. At the same time, it is also an indispensable product for technology construction. It occupies a lot of market share, mainly because of the strong function of electric ball valve, small size, reliable performance, large circulation capacity, light and cheap people, remote control and other reasons. Electric ball valve is not only throttling, cut-off, cutting, A good product for switching on and off, or the preferred fierce product in the flow regulation system. It has various characteristics such as pressure resistance, temperature resistance, corrosion resistance, small flow resistance, long service life and wide application range.
