Application:
The T402868 intake valve is designed for Perkins T4.236 and AT4.236 turbocharged 4.0L diesel engines. These engines are renowned for their balance of power and efficiency, making them suitable for a wide range of applications including agricultural machinery, construction equipment, and generator sets.Perkins 2306, 2506, and T4.236 series four-cylinder diesel engines (4.0 L displacement), widely used in agricultural tractors, generator sets, construction equipment, and industrial machinery. Specifically designed for the intake phase of turbocharged and naturally aspirated Perkins T4.236, AT4.236, 4.248, and A4.248 diesel engines.
Technical specifications:
Valve head diameter: 44.5-45.0 mm (typical for this engine series)
Stem diameter: 9.5 mm (0.374 inches) standard for Perkins large-bore six-cylinder engines
Overall length: 146-150 mm (5.75-5.90 inches) based on series design
Seat angle: 45° precision-ground sealing face
Stem type: Single-groove for split collet retention (standard 7° collet angle)
Tip configuration: Induction-hardened to resist wear from rocker arm contact
Valve guide clearance: 0.04-0.06 mm when used with CH10724 valve guides
Material & performance features:
Manufactured from high-grade austenitic steel alloy (21-4N derivative: 5Cr21Mn9Ni4N) providing 900 MPa tensile strength at 700°C operating temperatures. The head receives solution treatment at 1,150°C followed by age-hardening to achieve 28-32 HRC core hardness, while the stem undergoes gas nitriding to create a 0.02-0.04 mm deep surface layer exceeding 750 HV hardness. This combination resists scuffing during prolonged low-speed, high-boost operation and prevents micro-welding on the valve seat.
