The pneumatic flanged ball valve is a high-performance shut-off valve that utilises compressed air as its power source and features a flanged connection. By rotating the ball through 90°, it enables rapid control of the flow of media within pipelines, as well as flow regulation. Thanks to the high sealing integrity and strong pressure-bearing capacity of the flanged connection, combined with the rapid response characteristics of the pneumatic drive, it is widely used in industrial sectors such as petroleum, chemicals, natural gas, power generation and metallurgy. It serves as a core piece of equipment for achieving automated control within complex piping systems.
