Kirk Key has launched two new styles of integral valve interlocks that fit nearly every type and size of quarter and multi-turn valves. The series ensures safety for any potentially dangerous work area, such as power plants and pharmaceutical facilities. The quarter-turn and multi-turn interlocks both 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, including ball, butterfly and plug valves. The original lever is replaced with a sliding-lever interlock mechanism, preserving the original characteristics of the valve. The multi-turn lock attaches directly to valves including those that are gate, globe and gear-operated. The locks do not require a system shut-down, and installation does not compromise or invalidate pressure tests of the host valve. Manufactured entirely of 316 stainless steel with keyways protected by a gasketed dust cover, the series is built for long-term use in harsh, industrial environments.
