Product Overview

Intake Valve Part No.3802355 is a critical valve‑train component for 6BT5.9 diesel engine widely fitted on excavators and heavy‑duty construction machinery. It controls opening and closing of the air intake passage, feeding fresh air into combustion chamber to guarantee sufficient air supply for fuel combustion. This replacement intake valve resolves common faults including valve face wear, valve stem abrasion, cylinder air leakage, insufficient engine power and unstable idle speed caused by long‑time high‑temperature heavy‑load operation. Every intake valve passes strict hardness test, dimension inspection and sealing performance test before shipment.
