Worm Gear Operated Butterfly Valves

A worm gear operated butterfly valve is a type of butterfly valve that is actuated using a worm gear mechanism, allowing for precise control and easier manual operation, particularly in larger or high-pressure systems. The worm gear mechanism consists of a worm (a screw-like gear) and a worm wheel, which work together to reduce rotational speed and increase torque. This design makes it easier to manually open or close the valve, especially in high-pressure or large-diameter applications.

Worm gear operated butterfly valves offer several key advantages, including higher torque output with minimal manual effort, precise throttling capabilities for accurate flow control, and a self-locking mechanism that prevents the valve from back-driving under fluid pressure. These features make them especially suitable for larger-diameter valves and high-pressure systems, ensuring smooth, safe, and reliable operation.
