Ductile Iron Chainwheels allow operation of valves in high, hard-to reach locations by means of a slight pull on the galvanized single loop chain or s/s pocket type. A flexible design allows for the Chainwheel to be easily and securely clamped to an existing valve handwheel, or pinned to the valve stem directly.

All Chainwheels are furnished with universal plated steel attachment hardware which makes adaption to existing valves quick and easy or when the Chainwheel is to be pinned to valve stem, a ductile iron bushing can be provided which can be machined to suit valve stem dimensions. Bushing and Chainwheel will be pre-drilled with pinhole, and supplied with a stainless steel pin for customer mounting to valve stem.
