Cameron DYNATORQUE accessories include quarter-turn stainless steel gear operators designed for use with valves, dampers, and most other quarter-turn applications requiring a self-locking mechanism. For aggressive environmental conditions or corrosive applications, these operators have external components constructed of cast CF-8M stainless steel. They are completely sealed and are ideal for applications such as brewing, food processing, leaching operations, offshore platforms, and pulp and paper plants.
Gear operators with stainless steel internal parts also are available. DT21 is suitable for use with chainwheel operators; DT3 and DT7 are not suitable for chainwheel operation. (These actuators are not recommended for use with handwheels over 18-in diameter and are not recommended for use with any of our chainwheel options.)
Materials: Unit housings, covers, indicators, and bolting hardware are 300 series stainless steel.

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.
