Application:
The CH11021 intake valve is engineered for Perkins T4.236 and AT4.236 turbocharged 4.0 L diesel engines, ensuring precise air–fuel charge control and robust durability in demanding applications. In agricultural tractors—Massey Ferguson 265, 275, 290, 390T, 398; Landini 10000 Series; and Fiat 640—this valve maintains optimal cylinder filling under heavy plowing, seeding, and transport loads. Combine harvesters such as Massey Ferguson 750, 760, 850 and White 8600 Series rely on its reliable seating to sustain efficient engine breathing during extended harvest cycles. Perkins T4.236 generator sets by FG Wilson, KOHLER, and Fairbanks Morse (60 kVA–100 kVA) depend on the CH11021 to deliver stable prime and standby power with minimal smoke. Industrial machinery—stationary pumps, compressors, and hydraulic power units driven by the T4.236 engine—benefits from its fatigue-resistant design to reduce downtime under continuous or intermittent heavy-duty service.
Technical specifications:
Valve head diameter 43.00 mm; stem diameter 7.95 mm; overall length 121.50 mm; seat angle 45°; sealing face width 1.80 mm; valve face thickness 1.80 mm; stem tip hardness 55 HRC ± 2; induction-hardened case depth 1.2 mm; dimensional tolerance ± 0.03 mm; individual weight 35 g.
Material & performance features:
Each CH11021 valve is precision-forged from high-nickel–chromium alloy steel with controlled grain flow to resist thermal shock and corrosion. A vacuum heat treatment followed by deep gas nitriding on the stem enhances surface hardness and fatigue strength, while mirror polishing minimizes guide friction and prevents carbon build-up. The combustion face receives a nickel-chromium plating for improved thermal conductivity and oxidation resistance, then is CNC-ground to an exact 45° sealing geometry with uniform 1.80 mm contact width for a gas-tight fit. A balanced quench-and-temper process ensures uniform carbide distribution for long-term durability, and a black-oxide finish on the stem protects the valve during handling and assembly.
Interchange part numbers:
CH11021; compatible with Perkins 3142L061; Massey Ferguson 3361472M91; Landini 3148878M91; Fiat 4642004; Weichai-Weifu WGCH11021.
