The valve guide enables valve movement and stroke as a consequence of acceleration by camshaft and keeps the valve in the center of the valve seat. Valve guides are used to shoulder the side forces operating on the valve stem. They conduct part of the combustion heat from the valve head to the cylinder head. These extreme loads define the correct choice of material with appropriate characteristics for the valve guide, which is of critical importance for product quality.
The key characteristics of materials used for valve guides are low friction and high thermal conductivity. We are capable of manufacturing Engine Valve Guide , usually made from cast iron, aluminium bronze valve guide and Brass material valve guide.
