Valve Guides - 81-2625 TRW Engine Component
- Part Number: 81-2625
- Brand: TRW Engine Component
- Type: Valve Guides
Valve guides are a part of the gas distribution system designed to absorb incoming forces acting on the rod. The guide bush removes excess heat from the valve with design features that allow it to withstand high-speed conditions.
The usage of the valve guides
These parts also have another function of preventing oil from entering the combustion chamber. This contributes to longer valve life and slows down stem wear. TRW Engine Component brand Valve Guides remove most of the heat from them, which is especially important for exhaust manifolds.
For the manufacture of such parts, the following types of gray cast iron are used:
- With a pearlite structure - most often used for the manufacture of bushings, which are subject to standard requirements. Their main advantage is durability.
- With perlite and phosphorus - used in engines with medium requirements. Thanks to the phosphor mesh, the wear resistance of the products is increased.
Also, an alloy of metals such as aluminum, zinc and copper is widely used in production. An innovative solution is the use of cermets for the manufacture of such parts of the gas distribution system.
