The large hydropower ball valve manufactured by the company is a key project of the state grid, which is used in xianyou pumped storage station in fujian province. Ball valve diameter up to 4.5 meters, export diameter 2.3 meters, weight up to 120 tons. The manufacture of pumped storage ball valves has created the highest three problems of weight, volume and processing difficulty of ball valves in China, realizing the localization of large hydropower ball valves and replacing imported products.

The opening and closing part of the ball valve is a ball with a circular channel. It rotates around the axis perpendicular to the channel. The ball rotates with the valve stem so as to achieve the purpose of opening and closing the channel.The ball valve only needs to be rotated 90 degrees and a small torque to close tightly.According to the needs of working conditions, the assembly of different driving devices to form a variety of different control methods of ball valve, such as electric ball valve, pneumatic ball valve, hydraulic ball valve and so on
