Industrial DYNATORQUE 90

Quarter-turn worm-gear operator

Our industrial DYNATORQUE 90 worm-gear operators are designed for use with valves and dampers as well as most other quarter-turn applications requiring a self-locking mechanism. Cameron's flexible manufacturing process allows us to offer both standard construction and custom configurations for customer-specific applications.

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 gearbox housings are made from cast grey iron with ductile iron as an optional material. The product line offers a varied selection of alternate component materials to meet your application requirements.
