Shop gear-operated butterfly valves for industrial piping and fluid-control systems requiring controlled manual valve operation. This collection includes Midland Industries butterfly valves with ductile-iron bodies in sizes from 2 inches through 12 inches, with multiple seat, disc, and mounting configurations.
Butterfly Valves with Gear Operators
Gear-operated butterfly valves use a manual gearbox to turn the valve stem and disc. The geared mechanism provides greater mechanical advantage than direct lever operation, making it useful where valve size, operating torque, or application requirements call for more controlled opening and closing.
Ductile-Iron Gear-Operated Butterfly Valves
Valves in this collection use ductile-iron bodies with Buna-N or EPDM seats depending on the model. Available disc configurations include ductile iron and stainless steel, allowing valve construction to be matched to different fluid, temperature, and operating requirements.
The assortment includes flangeless and other mounting configurations across nominal sizes from 2 inches through 12 inches. Always confirm the individual valve dimensions, mounting requirements, and mating-pipe configuration before installation.
Choosing a Gear-Operated Butterfly Valve
Before ordering, verify nominal size, mounting style, body and disc material, seat material, pressure rating, operating temperature, media compatibility, and required flow characteristics. The valve and operator should also be properly sized for the torque requirements of the application.
For direct manual operation, browse our lever-operated butterfly valves. You can also view our complete butterfly valves collection for additional configurations.
