Product Overview

Exhaust Valve Part No.3802356 is an essential valve‑train component for 6BT5.9 diesel engine, widely equipped on excavators and various heavy‑duty construction machinery. It controls opening and closing of exhaust passage, and discharges high‑temperature burned gas out of combustion chamber during engine working cycles. This replacement exhaust valve solves common failures such as valve face ablation, valve stem wear, cylinder air leakage, insufficient engine power and abnormal exhaust smoke caused by long‑term high‑temperature heavy‑load operation. Each exhaust valve undergoes strict hardness detection, dimension inspection and sealing performance test before shipment.
