Application
The 3142L051/905-026 Intake Valve is precision-engineered for 4.4-liter, 6.0-liter, and 6.6-liter inline diesel engine platforms, specifically compatible with Perkins 1004, 1006, and 6.354 series power units. This valve is extensively utilized across heavy-duty agricultural machinery, construction equipment, material handling systems, and power generation units.
The valve regulates the intake of fresh air or fuel-air mixture into the combustion chamber, ensuring optimal engine breathing efficiency and volumetric efficiency. It is compatible with naturally aspirated and turbocharged diesel engines, supporting reliable operation in high-demand farming, earthmoving, and industrial power applications. The valve maintains critical sealing integrity during intake cycles, contributing to improved engine efficiency, reduced emissions, and optimal power output.

Material & Performance Features
The intake valve is manufactured from high-grade 21-4N austenitic heat-resistant stainless steel (containing 21% chromium, 4% nickel, and nitrogen additions) combined with chrome-manganese-nickel steel, providing exceptional heat resistance, wear resistance, and structural stability under cyclic high-temperature operating conditions.
The material composition ensures superior oxidation resistance and maintains mechanical properties at elevated temperatures encountered in modern turbocharged diesel combustion chambers. The valve features a chrome-plated valve stem with precision surface finish, significantly improving wear resistance, scuffing resistance, and fatigue life.
This surface treatment ensures minimal stem-to-guide wear and maintains precise valve seating geometry over extended service intervals. The solid metal rod construction (distinct from hollow sodium-filled exhaust valve designs) provides robust structural integrity for intake cycle operation.
