According to the shell material / material of main part, valve can decided into following parts:
1. Non-metal material valve: such as Caramic valve, Glass valve, Plastic valve.
2. Metal material valve: such as Carbon steel valve, Alloy steel valve, Stainless valve, Cast iron valve, Titanium alloy, Monel valve, Aldary valve, Aluminium alloy valve, Lead alloy valve and etc.
3. Metal body lining valve: such as Rubber liner valve, Fluorine liner valve, Lead liner valve, Plastic liner valve, Enamel liner valve.
