Ball valves were introduced in the 1950s. With the rapid development of science and technology and the continuous improvement of processes and product structures, they have rapidly developed into a major type of valve within just 40 years. In the industrialized countries of the West, the use of ball valves is increasing year by year. In China, ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, power, municipal services, and steel, playing a crucial role in the national economy.
Simple structure, small volume and light weight.
The ball valve is tight and reliable. Currently, plastic is widely used as the sealing surface material of the ball valve, which has good sealing performance and has also been widely used in vacuum systems.
It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for remote control.
The ball valve is easy to maintain. It has a simple structure and the sealing rings are usually movable, making disassembly and replacement relatively convenient.
When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve's sealing surfaces.
It has a wide range of applications. When the ball rotates 90 degrees, the entire spherical surface should be presented at the inlet and outlet to cut off the flow.
Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, power, municipal services, and steel, and play a crucial role in the national economy.
