How about the selection principle of Sanitary Ball Valve!

How about the selection principle of high platform ball valve! The ball valve is not only simple in structure and good in sealing performance, but also small in volume, light in weight, low in material consumption, small in installation size within a certain nominal diameter range, and has small driving torque, easy to operate, and easy to open and close quickly. It is one of the fastest growing valve varieties in the past decade.

1. For the main pipelines of oil and natural gas transmission, if the pipelines need to be cleaned and buried underground, full-diameter and fully welded ball valves should be selected; for those buried on the ground, full-diameter welded or flanged ball valves should be selected; for branch pipes, flanged, welded, full-diameter or reduced-diameter ball valves should be selected.

2. For the pipelines and storage equipment of refined oil, flange-connected ball valves should be selected.

3. For the pipelines of city gas and natural gas, floating ball valves with flange connection and internal thread connection should be selected.
4. For oxygen pipeline systems in metallurgical systems, it is advisable to use strictly degassing

5. For pipeline systems and devices for low-temperature media, it is advisable to use low-temperature ball valves with valve covers.

6. For pipeline systems of catalytic cracking devices in oil refining devices, lifting rod ball valves can be used.

7. For devices and pipeline systems for corrosive media such as acids and alkalis in chemical systems, it is advisable to use all-stainless steel ball valves made of austenitic stainless steel and with polytetrafluoroethylene as valve seat seals.

8. For pipeline systems or devices for high-temperature media in metallurgical systems, power systems, petrochemical devices, and urban heating systems, metal-to-metal sealed ball valves can be used.

9. When flow regulation is required, a worm gear-driven, pneumatic or electric regulating high-platform ball valve with a V-shaped opening can be used.
