7F-2454: 7.027" Long Exhaust Valve

An Exhaust Valve is responsible for regulating the flow of exhaust gases out of the combustion chamber. Positioned within the cylinder head, the exhaust valve opens and closes at specific intervals, synchronized with the engine's piston movements. As the piston reaches the end of the power stroke and begins its upward movement on the exhaust stroke, the exhaust valve opens, enabling the release of combustion by-products. Attributes: • Designed to achieve a hardness of 67-76 at the seat and 50-60 at the stem in the Rockwell test at 30N load • Resists chemical reactions with the air-fuel mixture and combustion by-products • Designed to withstand extreme pressure and temperature conditions Applications: An Exhaust Valve ensures the proper removal of exhaust gases from the engine cylinder and maintains the pressure during combustion.
