Electric flange ball valve

Electric flange ball valve

Electric flange ball valve is a type of rotary ball valve with a 90 "angle. It has excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, long service life, and the valve body channel and connecting pipe diameter are equal and form a diameter. The medium can flow almost without loss. It is equipped with HL actuator and is usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and steam media, it is also suitable for controlling media containing fiber impurities in water. Widely used in various fields such as petroleum, chemical, metallurgy, light industry, papermaking, power plants, refrigeration, etc.

Performance characteristics:

1. Low fluid resistance, the ball valve type has the smallest fluid resistance among all valve types, even for reduced diameter ball valves, its fluid resistance is quite small.

2. The thrust shaft bearing reduces the friction torque of the valve stem, allowing for long-term balanced and flexible operation of the valve stem.

3. The valve seat has good sealing performance, and the sealing ring made of materials such as polytetrafluoroethylene is easy to seal. Moreover, the sealing performance of the ball valve increases with the increase of medium pressure.

4. The valve stem seal is reliable. As the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.

5. Due to the good self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, and the service life of the ball valve is longer.
