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.

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.
