Product Details

    Electric flange ball valve is a type of ball valve with a rotation angle of 90 °. It has excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, and long service life. The valve body channel and connecting pipe diameter are equal and form a diameter, and the medium can flow through without loss. It is equipped with an LDV actuator, and the product is usually used in occasions with strict sealing requirements, except for controlling gas, liquid, and steam media, It is also suitable for controlling media containing fiber impurities in water, and is widely used in fields such as petroleum, chemical industry, metallurgy, light industry, papermaking, power plants, refrigeration, etc.

Performance characteristics of electric flange ball valves:

  1. The fluid resistance is small, and ball valves have the smallest fluid resistance among all valve types. Even for reduced diameter ball valves, their fluid resistance is relatively small.

  2. The thrust shaft bearing reduces the Friction torque of the valve rod, which can make the valve rod operate flexibly for a long time.

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

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

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