7F-2455: 7.027" Long Inlet Valve

An Inlet Valve is used to regulate the flow of air-fuel mixture into the combustion chamber. As the piston moves downward during the intake stroke, the inlet valve opens, allowing the mixture to enter the combustion chamber from the intake manifold. Once the cylinder is filled, the inlet valve closes to create a sealed chamber, ensuring efficient combustion and preventing any backward flow of gases. 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 air-fuel mixture and combustion by-products • Designed to withstand extreme pressure and temperature conditions Applications: An Inlet Valve ensures the proper inlet of air-fuel mixture into the engine cylinder and maintains the pressure during combustion.
