General information about this item
Product info
The B7-03-0631 ball valve functions as a check valve in the BMW 700 carburetor and stabilizes fuel pressure to ensure a consistent fuel-air mixture. During a carburetor overhaul, worn or corroded ball valves should be systematically replaced, as leaks significantly impair engine performance. Careful cleaning of the channels and the correct specification of the valve are essential for a restoration faithful to the original.
