Selecting the right materials not only extends valve service life but also reduces downtime for maintenance and lowers safety risks, making it a critical component for the stable operation of industrial systems.

The service life and corrosion resistance of valves depend 80% on material selection. For different media, temperatures, and pressure conditions, it is essential to match the valve with the appropriate material; otherwise, problems such as corrosion, wear, and leakage are highly likely to occur.
Cast iron: low cost; commonly used in ordinary service conditions such as ambient temperature, low pressure, clear water, and sewage; not resistant to strong acids, strong alkalis, or high pressure; currently being gradually replaced.
Carbon steel (WCB/WCC): Offers high mechanical strength and is suitable for medium- to high-temperature, medium-pressure service conditions involving water, steam, oils, and neutral gases, making it the most widely used material in industry.
Stainless steels 304 and 316L: These grades offer excellent corrosion resistance and heat resistance, making them widely used in applications involving chemicals, food, pharmaceuticals, and seawater. Among them, 316L is particularly well suited for environments containing chloride ions.
Duplex stainless steel combines the advantages of austenite and ferrite, exhibiting exceptional resistance to stress corrosion and pitting. It is commonly used in harsh environments such as offshore platforms, high-chloride media, and oil and gas extraction.
Hastelloy and Monel alloys: high-end corrosion-resistant alloys that can withstand strong acids, strong bases, and highly oxidizing environments, commonly used in specialized fields such as fine chemicals, nuclear power, and aerospace.
Fluoropolymer-lined, rubber-lined, and ceramic valves: Designed for highly corrosive and highly abrasive media, with internal linings of PTFE, rubber, or structural ceramics to provide dual protection against corrosion and wear.
Selecting the right materials not only extends valve service life but also reduces downtime for maintenance and lowers safety risks, making it a critical component for the stable operation of industrial systems.
