Pneumatic Triple Eccentric Butterfly Valve Technology

As a core fluid control solution represented by Pneumatic Triple Eccentric Rubber Lined Control Butterfly, this series of heavy-duty pneumatic butterfly valves also complements the product lineup alongside Pneumatic V-port PTFE Lined Control Ball Valve and Pneumatic O-port Cut-off & Control Ball Valve, catering to diverse cut-off and flow regulation demands in industrial piping systems. This butterfly valve adopts a U-shaped stainless steel elastic sealing ring, which forms three-eccentric matching contact with the polished disc. It overcomes the inherent defect of traditional eccentric butterfly valves: sliding friction between sealing surfaces within the 0°–10° opening range. Its unique structural design enables instant separation of sealing faces the moment the disc opens, and tight sealing contact immediately upon closing. This innovative structure greatly extends service life and delivers premium zero-leakage sealing performance. Suitable for working media with temperature u…
