Commercial Aluminum DYNATORQUE 90

Quarter-turn worm-gear operators

Our commercial aluminum DYNATORQUE 90 worm-gear operators are for use with valves, dampers, and most other quarter-turn applications requiring a self-locking mechanism. Our flexible manufacturing process allows us to offer both standard construction and custom configurations.

Standard operators are available with various mounting interface dimensions. Custom-machined gears come with bores and bolt holes for direct mounting to the valve. Standard housing material is aluminum.
