Application:

The U20176380 exhaust valve is designed for Perkins 400 series diesel engines, including models such as the 403D-15 and 404D-22. These engines are widely used in agricultural machinery (e.g., tractors), construction equipment (e.g., excavators), and generator sets. The exhaust valve ensures efficient expulsion of exhaust gases during engine overhauls, providing reliable performance under high-load conditions.

Technical specifications:

The U20176380 exhaust valve features a precision-machined design with a valve head diameter of 33 mm, a seat angle of 45°, an overall length of 99.6 mm, and a stem diameter of 7 mm. The valve is manufactured from high-quality alloy steel, ensuring excellent wear resistance and high-temperature performance.

Material & performance features:

The U20176380 exhaust valve is forged from high-grade alloy steel, offering superior durability and resistance to high temperatures and pressures. The induction-hardened stem tip and gas-nitrided layer on the lower stem enhance durability and prevent micro-welding, ensuring stable lash over thousands of hours of stop-start field service.
