It all depends on how you use the valve. For moving air, definitely not legal per R75 as it has no air pressure rating, per R76 as it has been heavily modified, and per R77 as it is not a part of the Kit of Parts nor is it functionally equivalent to a KOP item and doesn't appear anywhere on the accepted list.

If using it as a mechanical valve to transmit, say small game pieces. Totally legal
