Control Ball Valve

Control ball valves have evolved from plug valves, with the closing element being a sphere. They achieve fluid control by rotating the sphere 90 degrees around the valve stem axis. Control ball valves are primarily used for cutting off, throttling, distributing, and changing the flow direction of media in pipelines.

Applications

Control ball valves can be used in water conveyance systems, seawater pipeline systems, gas pipeline systems, and weak acid-base transport systems.
