ANSI Flange Butterfly Valve

A Flanged Butterfly Valve is a highly efficient quarter-turn valve designed for regulating and isolating the flow of liquids, gases, and slurries in industrial piping systems. Featuring flanged end connections, it can be securely installed between pipeline flanges, ensuring excellent stability and leak-tight performance. The valve consists of a circular disc mounted on a rotating shaft; when the disc turns 90 degrees, the valve opens or closes quickly, enabling precise flow control.

Manufactured from durable materials such as cast iron, ductile iron, carbon steel, stainless steel, and specialized alloys, flanged butterfly valves offer outstanding corrosion resistance and long service life. They are widely used in water treatment plants, power generation facilities, HVAC systems, chemical processing, oil and gas industries, and municipal infrastructure projects.

Key advantages include compact structure, lightweight design, low operating torque, easy maintenance, and cost-effective installation. Available with manual, electric, pneumatic, or hydraulic actuators, flanged butterfly valves can meet diverse operational requirements and automation needs. Their reliable sealing performance and efficient operation make them an ideal choice for modern industrial flow control applications.
