Chain Operators for Gate Valves. A chain operator is designed to be used for operating a valve in an overhead location. The chain operator attaches to a valve handwheel and a looped chain is fed thru one side of the operator and out the other. By pulling on the chain, the valve handle is turned to either open or close the valve.

For overhead, out-of-reach locations. The valve is operated by?pulling on the chain installed on round handwheel.
