Material classification of ball valves

Ball valves can be divided into the following main types according to their materials:
1. Stainless steel ball valve:
Features: corrosion-resistant, suitable for a variety of chemical media, with high strength and durability.
Application: widely used in chemical, petroleum, natural gas, food processing and other industries.
2. Carbon steel ball valve:
Features: high strength, low price, but poor corrosion resistance.
Application: commonly used in pipeline systems with low corrosive media such as water, oil and gas.
3. Brass ball valve:
Features: good thermal conductivity and electrical conductivity, more corrosion-resistant.
Application: mostly used in water heating systems, natural gas, liquefied petroleum gas and other household and commercial facilities.
4. Plastic ball valve (such as PVC, PP, PVDF and other materials):
Features: light weight, strong corrosion resistance, but poor high temperature resistance.
Application: suitable for corrosive media such as acid and alkali, widely used in chemical, environmental protection, water treatment and other industries.
5. Cast iron ball valve:
Features: high strength, moderate price, but poor corrosion resistance.
Application: Mainly used in ordinary pipeline systems such as water supply and gas supply.
6. Alloy ball valve (such as Hastelloy, Monel alloy, etc.):
Features: It has extremely high corrosion resistance and high temperature resistance.
Application: It is used under extreme working conditions, such as high temperature and high pressure, strong acid and strong alkali environment, etc.
When selecting the material of the ball valve, it is necessary to decide according to the specific working conditions, including the type of medium, temperature, pressure and other factors to ensure the safety, reliability and service life of the ball valve.
