Gear Box
Gear operated butterfly valve drives disc through worm gear, which opens and closes slowly but saves effort. In addition to saving labor, its sealing performance is also better than that of lever operated butterfly valve, especially in the environment with . high opening and closing frequency, the service life of gear operated butterfly valve will be longer than that of lever operated butterfly valve Lever operated butterfly valve is generally used with small diameters (below DN200), because butterfly valve with small diameter has small torque and can be directly opened and closed by hand, while gear operated butterfly valve uses a gearbox to drive the stem to rotate, which saves effort.
