WESPC Exhaust Valve 3142A111 for Perkins 1004 and 1006 series diesel engines

WESPC Exhaust Valve 3142A111 for Perkins 1004 and 1006 series diesel engines

Application:

The 3142A111 exhaust valve is designed for Perkins 1004 and 1006 series diesel engines, such as the 1004-4, 1004-4T, 1004-40S, 1004G, 1006-6T, 1006-6TW, and 1103C-33. 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 operation, providing reliable performance under high-load conditions.

Technical specifications:

The 3142A111 exhaust valve features a precision-machined design with a valve head diameter of 36.6 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 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 3142A111 exhaust valve 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.
