Used to Operate Overhead Valves from the Floor
Sprocket-Type, for use with Single Loop Cut Chain
ALUMINUM CHAINWHEELS allow operation of valves, actuators, or gear boxes in high, hard-to-reach locations by means of a slight pull on the chain. The light weight of aluminum Chainwheels is desirable to minimize the weight on the stems.This series of chainwheels is similar to our Ductile Iron Sprocket-type Chainwheels, in terms of chain type and handwheel ranges.
Universal design allows Chainwheel to be clamped to handwheel, or pinned directly to stem.
Furnished with stainless steel attachment hardware for clamping to handwheel. When Chainwheel is to be pinned to stem, “Star Adapters” are available (click HERE for PDF information sheet). Adapter is pre-drilled with pin hole, and supplied with a stainless steel pin for customer mounting to the stem.
Aluminum Chainwheels are provided with a protective coating.
To prevent serious injury, we recommend the use of our Secondary Safety Restraint System. All Trumbull Chainwheels are furnished with a threaded boss for the addition of our Safety Restraint System.
Ductile Iron and Aluminum Chainwheels are sprocket-type, using single loop cut chain. See also our Carbon Steel & Stainless Steel Pocket Chainwheels that use smooth welded link machine chain.
