Intake and Exhaust Valves are made from different materials to operate under different conditions. These are made from high grade Valve Steel Series - EN18D, EN24, EN52, EN54, EN59(214N) (Non-Magnetic/Bimetal).

The hardness of the Valve series varies from 20HRC to 50HRC according to the material used and the application of the Valve.

We generally use alloy steel for Intake Valve as these Valves are not Exposed to the Corrosive action of the hot Exhaust gases. Therefore, these are capable to serve longer periods with trouble free operations.

For the Exhaust Valve, Chromium Silicon is used which makes it resistant to corrosion due to high temperature and hot gases.

Engine Valves are also made with Chrome Plating for special purpose and are available in over sizes.

Engine Valves are made to suit many applications such as in Automobiles, Tractors, Industrial & Diesel Engines, Generators and Two Wheelers.
