VALVE BRIDGE

　　Tianxuan valve bridge is formed by multiple cold extrusion from low-carbon alloy steel, so it has a excellent forming precision. Compared with traditional technology, Tianxuan valve bridges have more complete fibrous tissue, finer grain size, better fatigue resistance, higher yield strength and better plasticity and toughness.

　　After carburizing on surface, the core of valve bridges has high toughness and on surface with a high hardness, which greatly improves the reliability of valve bridges.
