Manual Hold-Open Device with Limit Switches
Manual valve operation in absence of control pressure
Used with actuated gate valves sized 3-in or smaller with internal valve pressure up to 10,000 psi.
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.
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.
