INLET VALVE T150 EARLY
Inlet valve for the early Triumph T150 Trident triple engine, PN 70-6422.
This is the inlet valve for the early T150 Trident triple, part number 70-6422, also cataloged as V270. It's a cylinder head component that lives in the combustion chamber, opening to let the fuel/air mixture into the cylinder on the intake stroke before the exhaust valve does its job pushing spent gases out.

The catalog cross-references this one to the triples engine specifically, and other listings for this same number tag it as a long-pattern valve for the triples family, so it's built to that engine's head dimensions rather than the twins. Given the wear this part sees seated against the valve guide and rocker gear, it's worth having someone check clearances and seat condition when you're in there rather than just bolting it in and hoping.
We don't have extensive detail on file for this one beyond what's in the parts book, so if you're not sure it matches your head casting or you're working off a different parts diagram, give us a call before you order.
