WESPC Inlet Valve 1842913C1 for Perkins T4.236 turbocharged diesel engine

WESPC Inlet Valve 1842913C1 for Perkins T4.236 turbocharged diesel engine

Application:

The 1842913C1 inlet valve is specifically developed for Navistar International DT466, DT466E, and DT530 series diesel engines (7.6 L and 8.8 L displacements), which are widely recognized as workhorses in commercial and heavy-duty equipment sectors. These engines are extensively installed in International Harvester trucks (such as the International 4700, 4900, and 8100 Series medium-duty trucks), school buses, transit buses, and vocational vehicles (including dump trucks, concrete mixers, and utility service trucks).

Technical specifications:

The 1842913C1 inlet valve features a precision-engineered design tailored to Navistar DT series engine requirements. Key dimensional parameters include a valve head diameter of 45.2 mm (optimized to maximize airflow volume while maintaining a tight seal with the cylinder head valve seat), a stem diameter of 8.5 mm (ensuring a low-friction fit with the engine’s valve guides to minimize wear), and an overall length of 127.0 mm (matched to the cylinder head’s structural depth for accurate valve lift and seating). 

Material & performance features:

The 1842913C1 inlet valve is forged from high-strength nickel-chromium alloy steel (21-4N), a material selected for its exceptional high-temperature resistance, tensile strength (minimum 1,200 MPa), and fatigue durability—essential for enduring the repeated thermal cycling and mechanical stress of heavy-duty engine operation.
