Valve Description:
The exhaust valve is a component of the engine cylinder head that regulates the flow of exhaust gases leaving the engine combustion chamber during the exhaust stroke. It also helps dissipate heat from the combustion chamber and protects the engine from overheating.
Features
- Valve design is optimized for optimal exhaust gas flow.
- Manufactured to exact specifications for rugged durability, reliable performance and high efficiency.
Applications
The exhaust valve in the cylinder head acts as a regulator for exhaust gases leaving the combustion chamber during the exhaust stroke and is widely used in Cat engine motor graders, engines (piston), tree harvesters, OEM applications, excavators, Base Machine-COSG-336E HVG, Base Machine-COSG-336E L UHD, wheel dozers (for scrapers), articulated trucks, trucks (including truck dozers), wheel loaders, track loaders, engine common platform (C13), power systems, engine common platform (C9), track-type tractors, generator sets, drills, material handling, pipelayers, and paving equipment.
