TRUMBULL Stainless Steel Chainwheels allow operation of overhead valves by means of a slight pull on the chain. Universal design allows Chainwheel to be clamped to handwheel, or pinned directly to valve stem.
Designed for corrosive environments, TRUMBULL Stainless Steel Chainwheels are Type 316 investment steel castings. Ideal in chemical processing, outdoor installations, or salt water environments.
All Chainwheels are furnished with attachment hardware for clamping to handwheel. Pocket style chainwheels use smooth, welded link (proof coil) chain.
Handwheels with hubs projecting above the handwheel rim may cause interference with the attachment set stampings in some instances. Please consult Power Plus or send us a drawing of your handwheel to avoid attachment problems.
Chainwheels furnished standard with "B" attachment sets (see above chart)
For optional ranges, using "A" or "C" sets (see tables below)
For direct mounting to shaft only:
Stainless Steel Bushing, machined by customer
Stainless Steel Bushing, machined by Trumbull
** Optional hardware attachment sets are available to fit different ranges of handwheels
* D suffix denotes "Disc", used in lieu of standard clamping hardware
