Electric Flange Butterfly Valve with Lever Override — Extended Flange Design for Secure, Long-Pattern Installation
This Electric Flange Butterfly Valve features a distinctive double-flange, long face-to-face body design, offering enhanced structural rigidity and a longer sealing path compared to standard wafer or short-pattern flanged valves. The extended flange configuration, combined with a full circle of bolt holes on each side, provides exceptional joint strength and stability — making this valve well-suited for larger pipelines and systems where connection robustness is a top priority.
A key feature of this model is its lever-type manual override, positioned conveniently on the actuator housing for quick manual operation during power outages, commissioning, or emergency shutdown situations. Unlike handwheel-style overrides that require multiple turns to fully open or close the valve, the lever mechanism allows for faster manual actuation — a practical advantage in time-sensitive operational scenarios. The valve's soft-seal rubber lining, visible within the flow bore, ensures tight, bubble-tight shutoff while also providing a layer of internal corrosion and wear protection.
