Product Overview

Exhaust Valve Part No.3802967 is a critical valve‑train component for ISBe ISDe QSB ISF3.8 diesel engines widely applied on excavators and heavy‑duty construction machinery. It is responsible for opening and closing exhaust passages, discharging high‑temperature burnt exhaust gas out of combustion chamber during engine working cycles. This replacement exhaust valve solves common failures including valve face ablation, valve stem wear, air leakage, insufficient engine power and abnormal exhaust smoke caused by long‑time high‑temperature working. Each exhaust valve undergoes strict hardness detection, surface inspection and sealing performance test before shipment.
