Flange type electric ball valve LDBAA

Application Areas
This product is a 90 ° rotary ball valve with excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, and long service life. The valve body channel and connecting pipe diameter are equal and form a diameter, and the medium can flow almost without loss. With high-performance actuators such as JL and JLQ, the product is usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. It is widely used in various fields such as petroleum, chemical, metallurgical, light industry, papermaking, electric drilling, refrigeration, etc.

Product Features
1. The fluid resistance is small, and ball valves have the lowest fluid resistance among all valve types. Even for reduced diameter ball valves, their fluid resistance is quite small.
2. Thrust bearings reduce the friction torque of the valve stem, allowing for long-term operation and balance flexibility of the valve stem.
3. The valve seat has good sealing performance and is supported by sealing rings made of materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing ability of the ball valve increases with the increase of the medium.
4. The valve seat 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 excellent self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, which prolongs the service life of the ball valve.
One channel allows for flexible control of the merging or splitting of media in the other two channels (as shown in flow diagram B).
6. The bottom mounted valve stem and the protruding step at the head of the valve stem prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, the protruding step can also form a metal contact with the valve body to ensure the valve stem seal.
