Chain Operators for Butterfly Valves
A chain operator is designed to be mounted to the handwheel of a gear-operated butterfly valve. The chain operator is used for operating the valve in an overhead location where the hanging looped chain is accessible. A lock-link looped chain is fed through one side of the operator and out the other, then joined continuous by using the Masterlink or by mechanical fastening. By pulling on the chain, the valve handwheel is activated to turn the valve stem either counter-clockwise to open or clockwise to close the valve. Butterfly valves for use with chain operators must be gear-operated. Chain operators can be factory or field installed on Asahi/America Type-57P, 57IL, 57LIS, 56 and 75 butterfly valves.
Ideal Applications Include:
Overhead locations
- For use with 1-1/2″ – 24″ butterfly valves
