Materials Used in Valves:

Metallic materials (for the valve body and internal components such as the stem, ball and disc)

Nonmetal materials (for the gasket, packing and seat)

[Iron-based] Carbon steel and cast iron (An alloy consisting mainly of iron and carbon) Alloy steel (A steel to which one or more alloying elements, other than carbon, (e.g., Ni, Cr, Mn, W and Mo) have been deliberately added to achieve a particular physical property)

[Nonferrous] Copper alloy (Bronze, brass) Light alloy (Any one of various metal alloys consisting mainly of aluminum (Al) or magnesium (Mg) to which one or more alloying elements have deliberately been added  (e.g., Cu, Zn, Si))

[Rubber-based] EPDM (Ethylene-propylene rubber) NBR (Acrylonitrile-butadiene rubber) FKM (Fluoroelastomer)

[Plastic-based] PTFE (Polytetrafluoroethylene) PA (Polyamide resin)
