Engine Valve

Engine Valve

FAB VISION has pioneered the design, development and manufacturing of cost-effective. high-performance Engine Valves for various applications. We have the capacity and capability to develop and supply high-performance Engine Valves as per your requirements in accordance to the chemical and metallurgical specifications specified by you.

Intake and exhaust valves used in internal combustion engine are made from different materials to operate under different conditions. Inlet Engine Valves are made from Chrome Silicon Alloy Steel and Exhaust Engine Valves are made from Chrome Nickel Silicon Alloy Steel (to operate under high temperature and high stress conditions). Engine Valves are also supplied with Liquid Nitriding Process or Hard Chrome Plating which increases the surface hardening of the stem. With every valve design we strive to maximize durability through higher fatigue resistance and tensile strength.

VALVE INSERT

Our high chrome alloy and Nickel base valve seat inserts are best suited for use in light alloy and cast-iron cylinder heads as they offer good wear resistance at high temperature and high corrosive resistance.

VALVE GUIDE

VALVE GUIDES ARE MADE FROM TWO KINDS OF MATERIALS

• GREY CAST IRON :- GREY CAST IRON of peritic structure with high phosphorous content. The politic structure and the reticular phosphide distribution along with the good graphite formation give high wear resistance and improved running properties in poor lubrication conditio
• CUZNAI-ALLOY :- CUZNAI-ALLOY guides have excellent wear resistance and low coefficient of friction. Used for highest stressed guides. All our Cast Iron Guides are manufactured having minimum hardness of 95 HRB (210 BHN).
