3417779 Exhaust Valve For CUMMINS Diesel Engine Exhaust Valve Replacement Spare Part

3417779X Exhaust Valve (VALVE,EXHAUST) is a core valve component matched for CUMMINS series diesel engines. Installed inside cylinder head, it opens periodically to discharge exhaust gas after combustion and cooperates with intake valve to complete the engine gas exchange cycle.

This exhaust valve solves common malfunctions including valve head ablation, poor sealing, insufficient engine power and abnormal exhaust smoke caused by wear, deformation and carbon deposition of old exhaust valves.

Core Product Advantages

1. Premium Heat-Resistant Alloy Raw Material

   Special high-temperature alloy steel, excellent thermal fatigue resistance, withstand ultra-high temperature exhaust gas impact, effectively prevent valve head ablation and cracking.

2. Precision Machined Valve Head & Valve Stem

   Accurate conical sealing surface achieves tight fit with valve seat; finely ground valve stem minimizes friction with valve guide to avoid jamming.

3. Professional Surface Hardening Treatment

   Improved wear and corrosion resistance, reduce material loss during long-term high-frequency reciprocating movement and prolong service life.

4. Stable Performance Under Cold & Hot Alternation

   Maintain structural stability under frequent temperature fluctuation, suitable for continuous heavy-load operation of engineering machinery and heavy trucks.

5. Anti-Carbon Deposition & Oxidation Resistance

   Resist erosion of high-temperature exhaust, slow carbon accumulation and surface oxidation.

6. Standard Matching Specification

   Dimension 25cm8cm8cm, weight 0.23KG, perfectly fit supporting CUMMINS cylinder head assembly, direct replacement without secondary machining.

7. Strict Multi-Process Factory Inspection

   All exhaust valves pass straightness test, hardness inspection and sealing test, stable batch quality for engine overhaul factories and engineering fleets bulk procurement.
