Common valve material
1. Cast iron valves
Cast iron valves are a common material. They have good hardness and strength and can withstand greater pressure and temperature. At the same time, cast iron also has good corrosion resistance and is suitable for some common media pipelines, such as tap water, sewage, etc.
2. Stainless steel valves
Stainless steel valves have good corrosion resistance and wear resistance, and are not easy to rust and easy to process. Stainless steel valves have better pressure and temperature resistance than cast iron, and are suitable for some high pressure and high temperature occasions, such as chemical industry, electricity, etc.
3. Copper valves
Copper valves are widely used in water supply, oxygen production and other fields because they have good thermal conductivity and electrical conductivity, and can better transfer temperature and electrical energy. Copper valves have good corrosion resistance and are also suitable for some highly corrosive media occasions.
4. Alloy valves
Alloy valves usually refer to nickel alloys, titanium alloys, etc. These materials have good high temperature resistance and strong corrosion resistance, and are widely used in some special occasions, such as nuclear power, aviation, etc. At the same time, compared with stainless steel valves, alloy valves have higher temperature resistance.
In addition to the above common valve materials, there are some other materials such as plastic, ceramic, etc. Valves of different materials have their own advantages and disadvantages. When selecting a valve, factors such as medium, temperature, pressure and flow rate need to be considered. Only by selecting the appropriate valve material can the effectiveness and safety of fluid control be guaranteed.
