lockout/ tagout of pneumatic valves
(OP)
Dear colleagues
Plant safety regulations require the de-energizing of system when working on it including pneumatic valves. a recommendation was made to introduce lockable isolating valves in the system but the requirement has been specified to lock the actual process valve. there are hundreds of valves in the plant, replacement will be expensive so i wanted to explore modification of valves to introduce the lockout/ tagout system on current valves.
i have attached 3 pics of typical valve types in the plant. please assist with modification concepts for lockout/tagout system on the valves

The safety requires a physical block valve on the process line to hang the tags, but it could be located at some distance from the pneumatic valve
