1. For the main pipeline used for oil and natural gas transmission, as well as the pipe that needs to be cleaned and buried underground, the ball valve with full bore and fully welded structure should be selected.
2. For the pipe buried above ground, choose full bore ball valve with welded connections or flange connections. For branch pipes, pick ball valves with flange connections or welded connections, full bore ball valves or reduced bore ball valves.
3. Flanged ball valves should be used for the delivery line and storage equipment of the refined oil.
4. Floating ball valves with flange connections or female connections should be used for city gas pipes.
5. In the oxygen piping system of the metallurgical system, the trunnion mounted flanged ball valve with strict ungrease treatment should be selected.
6. The low temperature ball valve with a bonnet is an ideal choice for piping systems transporting low temperature media.
7. The lifting rod type ball valve can be used for the pipeline system of the catalytic cracking unit in a petroleum refinery.
8. Austenitic stainless steel ball valves with PTFE as the seat sealing ring material should be selected for devices and piping systems transporting the corrosive medium in the chemical engineering system.
9. The metal seated ball valve can be used for piping systems or devices transporting high-temperature media in metallurgical systems, power systems, petrochemical equipment and district heating systems.
10. When flow regulation is needed, the adjusting ball valve with v-shaped opening driven by worm gears, pneumatic actuators or electric actuators can be selected.
