Integrated with any size ball, plug, gate, butterfly, or globe valve, QL and GL Mechanical Valve Interlocks ensure potentially hazardous valve operations are performed in correct sequence, eliminating possibility of operator error or deliberate sabotage. Units are 316 SS for long-term operation in harsh onshore and offshore conditions. Operation is by cast stainless steel coded card keys, which push in and pull out of weather-sealed apertures in lock body.
