4- to 6-in-Valve Manual Hold-Open Device
Threads directly to the top of the actuator
Manually operate the valve when control pressure is not available.
Handwheels
Fabricated for reliability
Our handwheels are suited for use with all of our quarter-turn and multiturn operators, manual overrides, and position indicators. Additionally, handwheels can be fitted to products manufactured by others, or, in some applications, be mounted directly to valve stems.
- 6- to 10-in handwheels are recessed, cast ductile iron
- 12- to 48-in handwheels are manufactured from tubing and available in standard recessed and optional flat configurations as well as in stainless steel
- Tubular handwheels are epoxy powder coated
- Cast handwheels are e-coated
- Additional diameters and interface machining available
Materials
Handwheel rims and spokes are constructed of high-quality 1-in-OD tubing. Handwheel hubs are constructed of cold-rolled carbon steel machined to your specifications.
Note: Use of cheater bars voids warranty. Assembling chainwheels to handwheel rims increases the weight and cantilever length and is not recommended. DYNATORQUE chainwheel adapters are recommended whenever using a chainwheel with a DYNATORQUE product gear. DYNATORQUE product recommends the use of our chainwheel adapters in lieu of handwheels in these applications.
