Introduction to Butterfly Valves

Butterfly Valve Series is a compact quarter-turn flow control device, designed for efficient and cost-effective fluid regulation. It uses a rotating disc mounted on a central shaft to control flow, requiring a 90-degree turn of the handle or actuator to open or close. Core components include valve body, disc, stem, sealing seat, and actuator (manual, pneumatic, or electric). It features lightweight structure, quick operation, and reliable sealing performance, suitable for large-diameter pipelines and low to medium pressure systems. Widely used in water treatment, food processing, and chemical industries, it ensures stable flow control with easy installation and low maintenance.
