Used to Operate Overhead Valves from the Floor

Sprocket-Type, for use with Single Loop Cut Chain

DUCTILE IRON CHAINWHEELS allow operation of valves, actuators, or gear boxes in high, hard-to-reach locations by means of a slight pull on the chain. Universal design allows Chainwheel to be clamped to handwheel, or pinned directly to valve stem.

Ductile iron Chainwheels are furnished with plated steel attachment hardware for clamping to handwheel. When Chainwheel is to be pinned to valve 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. Drilling of valve stem by customer. 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.
