Butterfly valves are widely used in many industries, including water treatment, oil and gas, and chemical processing, due to their compact design, ease of operation, and low cost.

The term butterfly valve might evoke the delicate image of a butterfly, with its wings gently fluttering in the breeze. However, in the realm of engineering and mechanics, a butterfly valve serves a robust and critical function far from the fragility its name suggests.

The sealing principle and structural characteristics of flanged butterfly valves are the same as those of ordinary centerline butterfly valves.

The opening and closing part of the flanged butterfly valve is a flange. The movement direction of the flange is perpendicular to the direction of the fluid. The flanged butterfly valve can only be fully opened and fully closed and cannot be adjusted or throttled.
