The valve is a kind of equipment widely used in various industrial and civil fields, and the choice of its material directly affects the performance and service life of the valve. When choosing the valve material, it is necessary to consider various factors according to the actual working conditions and use requirements to choose the most appropriate valve material.

Metallic material
1.Carbon Steel
Carbon steel is a common valve material with high strength and corrosion resistance and is suitable for most industrial fluids such as water, steam, petroleum and certain chemical fluids. The price of carbon steel valves is relatively low and is widely used in various industrial fields.
2.Stainless Steel
Stainless steel is a high corrosion resistance and aesthetic metal valve material, widely used in food, pharmaceutical, chemical and other industries in the fluid pipeline. Stainless steel valves usually have good mechanical properties and high temperature resistance, and can resist the erosion of a variety of corrosive media.
3.Cast Iron
Cast iron is a metal valve material with high strength and wear resistance, suitable for water, steam and sewage and other media. The price of cast iron valves is relatively low, which is suitable for some occasions where the sealing performance is not high. Copper Alloys have excellent corrosion resistance and processing properties, and are widely used in water, steam and air conditioning systems. Copper alloy valves usually have good sealing performance and long service life, and are suitable for some occasions with high requirements for fluid quality.
Non-metallic material
1.Plastics
Plastic is a kind of non-metallic valve material with characteristics of lightweight, corrosion resistance and not easy to rust, which is widely used in corrosive media in chemical, petrochemical, pharmaceutical and other industries. Commonly used plastic valve materials are polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and so on.
2.Rubber
Rubber is a non-metallic valve material with good elasticity and sealing properties, which is widely used in water, steam, air and other media. Rubber valves are usually cheaper and suitable for some occasions with low sealing performance requirements.
3.Ceramic
Ceramic is a non-metallic valve material with high corrosion resistance and high wear resistance, which is suitable for a variety of highly corrosive and high wear media, such as concentrated sulfuric acid, lye, high temperature steam and so on. Ceramic valves have a long life and are suitable for some special occasions, but their manufacturing costs are higher.
4.Fluoroplastic
Fluorine plastic is a kind of non-metallic material with high corrosion resistance and high temperature resistance, which is widely used in a variety of highly corrosive media. Fluorine plastic valves usually have better sealing performance and service life, suitable for some special industrial fields, such as chemical, pharmaceutical and so on.
