Babbitt Chainwheels

Operate Hard-to-Reach Valves From the Floor

A Babbitt chain wheel, also referred to as a chainwheel, attaches to the existing handwheel of a valve and lets it be opened and closed from the floor instead of a ladder or lift. Paired with a chain guide, it operates valves mounted in high or otherwise out-of-reach locations easily and economically. Babbitt chain wheels fit handwheels ranging from 2 to 36 inches in diameter, covering most manually operated valves found in a typical plant.

 

Six Chain Wheel Styles, One Job

Babbitt offers six chain wheel configurations, each suited to a different mounting or operating condition:

• Standard Chainwheel: The baseline configuration for most manual valve applications.

• Hammer-Blow: Adds a driving mechanism that delivers extra torque on the final turn, useful on valves that have seated tightly or seen infrequent use.

• Solid Hub Chainwheel: Mounts without a split hub, for installations where the wheel doesn't need to come off the valve for service.

• Safety Wheel: Guards the wheel to reduce pinch points and chain entanglement risks in walkways and high-traffic areas.

• Pocketwheel: Uses machined pockets to keep the chain tracking correctly, typically specified on larger-diameter wheels.

• Chain Bar: A rigid-bar alternative to a wheel and chain for shorter-reach applications.

   

Chain, Masterlinks, and Quick Links to Complete the Chain Wheel

A chain wheel is only as good as the chain running through it. Babbitt offers weldless chain for lighter-duty applications and welded chain where higher-cycle or heavier-duty use calls for it. The Babbitt Masterlink and Quick Link let the loop be closed, shortened, or reopened in the field without cutting or rewelding, which matters when a chain needs to be resized to match a new valve height.

Lock-Out, Safety, and Attachment Accessories

Beyond the wheel and chain, Babbitt supplies the hardware that keeps a chain-operated valve safe and serviceable. Lock-Out/Tag-Out systems support LOTO compliance during maintenance. 

Safety Cable Kits and Safety Cap Kits help contain the chain if a component fails. Hammer-Blow Conversion Kits and Attachment Sets let an existing standard wheel be upgraded rather than replaced. 

Stainless Steel Attachment Sets and Tags are available for washdown or corrosive environments, and the Babbitt Bucket keeps excess chain off the floor and out of the way.

Get the Right Chain Wheel Configuration for Your Valve

Guessing at a chain wheel configuration is how the wrong wheel ends up bolted to the wrong valve, and downtime costs a lot more than a five-minute call would have. Give the factory your handwheel diameter, mounting orientation, and operating environment, and they will match you to the chain wheel, chain length, and accessories that actually fit the job, the first time.
