TRUMBULL stainless steel chainwheels provide safe, easy operation of overhead valves with a simple pull of the chain. Their universal design allows for mounting directly to the valve stem or clamping to an existing handwheel.
Constructed from Type 316 investment-cast stainless steel, these chainwheels are ideal for corrosive environments such as chemical processing, outdoor installations, and saltwater applications. Each unit includes attachment hardware, and pocket-style models are designed for use with smooth, welded link (proof coil) chain.
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
