● It has the advantages of high intelligence, complete functions, stable and reliable performance, and the flow resistance coefficient is very small, and the flow resistance coefficient is equal to that of the pipeline when it is fully opened. It can be designed separately according to the special requirements of users, so as to meet the needs of users.

● The electric control system adopts PLC intelligent control, which greatly simplifies the electric circuit and has strong fault self diagnosis function. It can be controlled locally and remotely, controlled by the central control room and the hydraulic turbine, with high degree of automation, safety and reliability, realizing the management concept of "few people on duty and no one on duty".

● The hydraulic control system uses heavy hammer to store energy. When the hydropower station has no power supply, the heavy hammer can release energy, which can realize emergency dynamic water closing ball valve, and provide sufficient safety guarantee for the safe operation of the unit.

● It is suitable for a wide range of water head, which can reach more than 1000 meters of water head.

● The fluid resistance is small, the ball valve is one of the smallest in all kinds of valves, even the reduced ball valve, its fluid resistance is quite small. As long as the valve rod rotates 90 ° the ball valve can be fully opened or closed, and it is easy to open and close quickly.
