Butterfly valves are widely used flow control devices designed for quick shut-off and regulation of liquids and gases in pipeline systems. Featuring a compact structure and lightweight design, the valve operates by rotating a disc within the valve body, allowing efficient control with minimal torque.

Available in wafer, lug, and flanged connection types, these valves can be operated manually by lever or gearbox, or automated with pneumatic and electric actuators. With reliable sealing performance, low pressure loss, and easy installation, they are commonly applied in water supply, HVAC, chemical processing, and power generation.
