Industrial Double Flange Butterfly Valve Supplier
A double flange butterfly valve is a heavy-duty butterfly valve designed with full flanges on both sides of the body for secure bolting to the pipeline. Compared with wafer and lug butterfly valves, double flange butterfly valves provide stronger installation stability, especially in large diameter, high flow, and critical pipeline systems.
As a professional double flange butterfly valve manufacturer, Wenzhou Zoncic Machinery Technology Co., Ltd supplies industrial double flange butterfly valves in ductile iron, carbon steel, stainless steel, and other materials according to pressure class, seat type, disc material, and working conditions. Our products are widely used in water treatment, power stations, chemical processing, seawater systems, and industrial utility pipelines.
