Dynatorque 360 Multiturn Worm Gears
Built for multiturn control where the driven equipment defines end positions
Designed for rotational equipment that does not require thrust loading.
Dynatorque handwheels
Suitable for Dynatorque and Maxtorque gears and accessories
Overview
Engineered to support dependable and ergonomic manual operation
Dynatorque™ handwheels are suitable for Dynatorque and Maxtorque™ gears and manual overrides as well as Dynatorque D-Lock™ valve-locking devices. Available in cast and fabricated designs, they help operators apply controlled rim pull for valve actuation while maintaining compatibility with a wide range of standard and customized gear configurations.
The handwheels can be used wherever manual input is required for valve gear operation, retrofit work, or accessory integration. They are suitable for quarter-turn and multiturn worm gears, multiturn bevel gears, spur gears, declutchable and nondeclutchable manual overrides, and field-mounted locking devices.
Applications
- Manual operation of worm, bevel, and spur gears
- Valve packages requiring controlled handwheel rim effort
- Manual override and valve-locking device assemblies
- Manual operation of gate, globe, plug, butterfly, and ball valves where power actuators are not required
Benefits
- Improved manual operation: Enabling controlled rim pull for reliable valve actuation
- Flexible configuration: Available with various diameters, styles, and hub interfaces
- Enhanced durability: Cast and fabricated designs to support industrial valve service
- Simplified retrofits: Standard bores or custom machining to support your requirements
Features
- Cast, ductile iron, recessed handwheels with 6- to 10-in diameters
- Fabricated, carbon steel, recessed handwheels with 12- to 48-in diameters
- Fabricated flat handwheels made of carbon steel or stainless steel, with 12- to 36-in diameters
- Fabricated, stainless steel, recessed handwheels available for select applications
- 1-in-OD tubing used for fabricated rims and spokes
