Durable Pneumatic Double Eccentric Butterfly Valve

As a reliable quarter-turn fluid control device, the Pneumatic Double Eccentric Butterfly Valve works alongside Pneumatic Triple Eccentric Rubber Lined Control Butterfly, Pneumatic V-port PTFE Lined Control Ball Valve and Pneumatic O-port Cut-off & Control Ball Valve to deliver complete fluid shut-off and modulating solutions for diversified industrial pipelines. This valve features a professional double eccentric structure: the valve stem deviates both from the disc center and the valve body’s sealing centerline. The design enables the sealing surface to separate from the valve seat the instant the disc opens, eliminating friction and abrasion during full opening and closing cycles. It delivers an unobstructed flow path with lower flow resistance than gate valves, relying on a simple 90-degree stroke for operation. Without extra accessories, it serves as a tight shut-off valve; when matched with a valve positioner, it can perform precise flow regulation under complex working con…
