WESPC Valve Inlet U20166380 for Perkins 400 series diesel engines

Application:

The U20166380 valve inlet is designed for Perkins 400 series diesel engines, 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 valve inlet ensures efficient air intake during engine operation, providing reliable performance under high-load conditions.

Technical specifications:

The U20166380 valve inlet features a precision-machined design with a valve head diameter of 37.0 mm, stem diameter of 7.0 mm, and overall length of 99.6 mm. It is manufactured from high-quality cast iron, ensuring excellent wear resistance and durability. The valve inlet has a seat angle of 45° and undergoes advanced gas nitriding treatment to enhance surface hardness. The head and stem are CNC-finished to Ra 0.2 µm to guarantee positive sealing and uniform heat transfer every cycle.

Material & performance features:

The U20166380 valve inlet is forged from high-grade cast iron, offering superior durability and resistance to high temperatures and pressures. The advanced gas nitriding treatment enhances surface hardness, while the chrome-plated top ring surface reduces friction and valve-guide wear. The tulip profile is swirl-polished to improve flow efficiency and reduce pumping losses, contributing to cleaner combustion and lower fuel consumption across the engine map.
