Fitting most types and sizes of quarter- and multi-turn valves, Kirk Key Eagle Lock Series integral valve interlocks seamlessly integrate to the valve body and do not void the valve warranty. The quarter-turn valve lock attaches to any type of lever-operated valve; the original lever is replaced with a Kirk sliding-lever interlock mechanism, preserving the original characteristics of the valve.
