An exhaust valve does the same job on any four-stroke twin: it opens to let spent combustion gases out of the cylinder and seals tight on the seat the rest of the time, so condition and fit in the guide matter more than most engine internals. Since this is a BSA A65 part and not a Triumph piece, don't cross it over into a Triumph head without checking dimensions first.
We don't have additional catalog detail on file beyond the replacement note, so if you're matching this against an existing engine, bring the old valve or the head specs with you and we'll confirm before you order.
