Several Necessary Conditions For The Selection Of Threaded Ball Valve

Several key considerations are essential for Threaded Ball Valve:
1. For oil and natural gas main pipelines that require cleaning and are buried underground, use full-bore, fully welded ball valves. For buried pipelines, choose full-bore welded or flanged ball valves. For branch pipes, choose full-bore or reduced-bore ball valves with flanged or welded connections.
2. For refined oil pipelines and storage equipment, use flanged ball valves.
3. For city gas and natural gas pipelines, use floating ball valves with flanged or internally threaded connections.
4. For piping systems and equipment in metallurgical systems, use strictly degreased, flanged fixed ball valves.
5. For piping systems and equipment carrying cryogenic media, use cryogenic ball valves with bonnets.
6. For piping systems in catalytic cracking units within refineries, use lift-type ball valves. 7. For chemical systems handling corrosive media such as acids and alkalis, all-stainless steel ball valves made of austenitic stainless steel and with polytetrafluoroethylene seat seals are recommended.
8. Metal-to-metal sealed ball valves are suitable for piping systems or devices handling high-temperature media in metallurgical systems, power systems, petrochemical plants, and municipal heating systems.
9. When flow regulation is required, worm gear-driven, pneumatic, or electric regulating ball valves with V-shaped openings can be used.
