could anyone please let me know where I could purchase a wheel key. Used for opening and shutting valves which are tight. I know this is not the correct way to operate a valve but its done no harm if used correctly. I've used them many years ago in the RN unfortunately mine has now been lost by a colleague.
If I understand you correctly,you mean a metal handle that has two fingers on,one of which can loop round and grip a round valve wheel ? Used to see them in use on chemical sites when I was a tanker driver - would suggest plant equipment supplier,or someone like ARCO.
