VALVES made from steel (bimetal, magnetic and non magnetic), Inlet valve made chrome-silicon alloy steel and exhaust from chrome-nickel-silicon alloy steel (to operate under high temperature and high stress conditions). Valves stem are hard chrome plating which increases the surface hardening and wear resistance of the Stem. This improves resistance to corrosion with consequent sliding ease.
