Trunnion ball valves are very common in many industries with medium to high pressure and complex working conditions.

Fixed ball valves are very common in many industries with medium-to-high pressure and complex working conditions. Fixed ball valves are the preferred choice for any medium-to-high pressure, large-caliber, highly corrosive or extreme temperature media transportation and control occasions. Especially in the following scenarios with high requirements for sealing, pressure resistance and wear resistance, they are widely used:
Common application industries of fixed ball valves
1. Oil and gas industry: Long-distance pipeline system: Fixed ball valves are often used in trunk pipelines for transporting crude oil and natural gas due to their strong pressure resistance and good sealing performance.
2. Oil production station/gathering station: Can be used for fluid control in ground gathering and transportation systems. Natural gas processing plant, LNG terminal: strong adaptability to high pressure and low temperature conditions.
3. Petrochemical industry: Suitable for the control of a variety of corrosive and flammable media, such as benzene, olefins, sulfides, etc. Used in key control points such as oil refining units, chemical reaction systems, storage and transportation systems.
4. Power industry: Especially in thermal power plants, used to control high-temperature steam, water, hot oil and other media. Applicable to high temperature and high pressure parts such as boiler main steam valve and water supply system.
5. Metallurgy and mining: Environments with many solid particles and strong media wear, such as coal powder, slurry, washing water and other conveying systems. The metal hard seal design of the fixed ball valve can effectively prevent wear.
6. Municipal and environmental protection: Used in sewage treatment, garbage incineration, power plant desulfurization and other systems, suitable for corrosive or particle-containing media. The structure is stable and suitable for large-diameter valve scenes.
7. Chemical and pharmaceutical: Places with high control accuracy requirements for corrosive liquids and gases, such as acids, alkalis, salts, and chemical solvents. The metal sealing material can be customized according to the properties of the medium, and it is highly safe.
8. Marine engineering and ships: Strong corrosion resistance and pressure resistance, suitable for seawater systems and platform high-pressure systems.
