Metal Materials

- Carbon Steel-

Carbon steel is a common valve material with high strength and corrosion resistance, suitable for most industrial fluids such as water, steam, oil and some chemical fluids. Carbon steel valves are relatively cheap and widely used in various industrial fields.

- Stainless Steel-

Stainless steel is a valve material with high corrosion resistance and aesthetics, widely used in fluid pipelines in food, pharmaceutical, chemical and other industries. Stainless steel valves usually have good mechanical properties and high temperature resistance, and can resist erosion by a variety of corrosive media.

- Cast Iron-

Cast iron valves have high strength and wear resistance, suitable for media such as water, steam and sewage. The price of cast iron valves is relatively low, suitable for some occasions where sealing performance is not required.

- Copper Alloys-
Copper alloys have excellent corrosion resistance and processing performance, and are widely used in water, steam and air conditioning systems. Copper alloy valves usually have good sealing performance and long service life, suitable for some occasions where fluid quality requirements are high.

Non-metallic materials

- Plastics-
Plastic valves are lightweight, corrosion-resistant, and not easy to rust. They are widely used in corrosive media in the chemical, petrochemical, and pharmaceutical industries. Commonly used plastic valve materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc.

- Rubber-
Rubber valves have good elasticity and sealing performance and are widely used in media such as water, steam, and air. Rubber valves are usually cheaper and suitable for some occasions where sealing performance is not required.

- Ceramic-
Ceramic valves have high corrosion resistance and high wear resistance and are suitable for various highly corrosive and highly abrasive media, such as concentrated sulfuric acid, alkali solution, and high-temperature steam. Ceramic valves have a long life and are suitable for some special occasions, but their manufacturing cost is high.

- Fluoroplastic-
Fluoroplastic is a non-metallic material with high corrosion resistance and high temperature resistance, which is widely used in various highly corrosive media. Fluoroplastic valves usually have good sealing performance and service life, and are suitable for some special industrial fields, such as chemical industry, pharmaceutical industry, etc.
