Ball valves evolved from plug valves, and their opening and closing parts act as a ball, using the ball to rotate 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing.

In building piping systems, fully welded ball valves play a role in controlling fluids. Due to differences in structure and material, the fully welded ball valves manufactured are also different.

The integrated welded ball valve is developed by absorbing advanced foreign technology and combining with the actual situation in China, replacing imports with domestic products to fill the domestic gap.

Common faults of ball valves include inadequate opening and closing of the ball valve, damage to the sealing surface, and the occurrence of pressure holding and jamming.

The ball valve is easy to operate and can be opened and closed quickly. It only needs to rotate 90 ° from full open to full close, making it convenient for remote control.

Ball valves were introduced in the 1950s. With the rapid development of science and technology, continuous improvement of production processes and product structures, they have rapidly developed into a major type of valve in just 40 years.
