Cameron DYNATORQUE valve accessories include gear operators that are modified with an infinitely adjustable memory-stop device suitable for valves, dampers, and most other quarter-turn applications requiring a self-locking mechanism.
This configuration is ideal for use when a valve or damper is used for flow control and must always be opened or closed to the same exact position. The addition of a traveling nut module allows repeatable valve travel to the predesignated set point.
Our flexible manufacturing process enables 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 materials are cast gray or ductile iron, and our extensive portfolio offers a varied selection of alternate materials to meet customer application requirements.

Handwheels listed are recommended sizes to produce full rated torque with the rim effort listed. The formulas listed below will assist you in determining alternate handwheel sizes and rim pull requirements based on your application.
- To find handwheel diameter for given output torque at a given rim effort, divide the output torque by the mechanical advantage and multiply the result by 2. Then divide this result by the handwheel rim effort.
- To find rim effort for a given output torque with a given handwheel diameter, divide the output torque by the mechanical advantage and multiply the result by 2. Then divide this result by the handwheel diameter. Handwheels are not included as part of the operator part list or price.
Bore, keyways, and mounting patterns listed are for Cameron standards. Please consult us for special bore treatments, costs, and deliveries.
Standard mounting patterns on the DT3 through the DT54 are four tapped holes straddling centerline at 45°.
