I use a Rover K series 16 valve exhaust valve on my flash steamer part No LGH 10028 which is an excellent material for my flash steamer inlet valve.
Rover part No LGH 101190 are some new valves that I have acquired they are the same dimensions as above but want to check if it is a similar material to above.
A long time has been spent on the computer trying to find the material of them with no success.
Any clues where to look as if not a suitable steel valve failure is inevitable.
There is still no email notification so have to check my bookmarks for replies.
