Application
The 3142H091 Intake Valve is precision-engineered for 4.4-liter and 6.6-liter inline diesel engine platforms, specifically compatible with 1104D and 1106D/E/C series power units. This valve is extensively utilized across heavy-duty construction equipment, including 20-ton class hydraulic excavators (320D, 323D, 326D, 329D, 336 models), agricultural tractors, telescopic handlers, and material handling equipment.
The valve regulates airflow into the combustion chamber, ensuring optimal engine breathing efficiency across agricultural tractors (Massey Ferguson 6400 and 7000 series), telescopic lifts (Doosan DT series, Manitou MLT series), and road construction machinery (Voegele Super series). It is compatible with turbocharged and aftercooled diesel engines featuring electronic fuel injection systems, supporting reliable operation in high-demand earthmoving, farming, and industrial power generation applications.
Designed to withstand high combustion chamber pressures typical of modern turbocharged diesel engines

Material & Performance Features
The intake valve is manufactured from high-grade 4Cr9Si2 martensitic heat-resistant alloy steel, featuring exceptional creep resistance and thermal fatigue strength under cyclic high-temperature operating conditions. The material composition includes chromium and silicon additives providing superior oxidation resistance and structural stability at elevated temperatures encountered in modern turbocharged diesel combustion chambers.
The valve undergoes advanced gas nitriding surface treatment, creating a hardened diffusion layer that significantly improves wear resistance, scuffing resistance, and fatigue life. This surface hardness treatment ensures minimal stem-to-guide wear and maintains precise valve sealing geometry over extended service intervals. The 30-degree face angle is precision-ground to ensure optimal seating contact pressure and combustion sealing capability.
