Norton Valve Exhaust
Norton exhaust valve for the cylinder head, part number 063282.
This is an exhaust valve, part number 063282, and the catalog places it right where you'd expect - in the cylinder head and valve gear area of the engine. The figure titles tag it under Cylinder, Cylinder Head and Fittings as well as Valve Gear, which lines up with what an exhaust valve does: it seats in the head and opens to let spent gases out of the combustion chamber before the next intake stroke.

The manufacturer tag on this one points to Norton, and nothing in the description contradicts that, so we're treating it as a Norton part rather than a Triumph one. Our catalog record shows it appearing across 1971 to 1973, but we don't have a specific model tied to it beyond that.
Exhaust valves take a beating from heat and combustion byproducts over the years, so if you're pulling the head for any reason it's worth having this one checked for seating and wear regardless of mileage. Call the shop if you want us to confirm fitment against your particular engine before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
