The Cameron commercial-grade DYNATORQUE 360 multiturn worm-gear operator is made for applications that require multiple output turns but do not require the operator to withstand thrust loading. These operators do not have positive output stops. Operators listed have bores, keyways, and mounting dimensions as listed on the individual operator envelope drawings. Operators are assembled in position II (clockwise input results in clockwise output) and have one shop coat of black oxide primer. Operator pricing does not include handwheels.
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, but the line also offers a varied selection of alternate materials to meet customer application requirements.

† Indicates units with spur assist.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. Consult Cameron for special bore treatments, costs, and deliveries.
Standard mounting patterns on the DT3 through the DT54 are four tapped holes straddling centerline at 45°.
