KB50V
Pneumatic V-Port Ball Valve
Design Features
The pneumatic V-port ball valve features a V-shaped notched ball core enabling equal percentage flow control through rotation. It is equipped with a precision pneumatic actuator (integrated positioner for precise throttling control), with valve seats available in hardened sealing or reinforced PTFE materials to handle fibrous and particulate media. The valve body flow passage is optimized to minimize buildup.
