Butterfly valves are primarily used for fluid control and safety management in the oil and gas industry.
A butterfly valve uses a disc-shaped opening and closing member that reciprocates approximately 90 degrees to open, close, or regulate the flow of a medium. Butterfly valves not only feature a simple structure, small size, light weight, minimal material consumption, small installation dimensions, low actuation torque, and easy and quick operation, but also offer excellent flow regulation and sealing properties. They have been one of the fastest-growing valve types in the past decade or so. Their use is widespread, and their variety and quantity continue to expand, with applications encompassing high temperature, high pressure, large diameters, high sealing performance, long life, excellent regulating characteristics, and multi-functionality. Their reliability and other performance indicators have reached high levels.
Butterfly valves have a small overall length and height, offer fast opening and closing speeds, and possess excellent fluid control characteristics. The structural principle of butterfly valves is most suitable for large-diameter valves. When using a butterfly valve for flow control, it is crucial to select the correct specifications and type for proper and effective operation. Generally, butterfly valves are recommended for throttling, regulating, and slurry applications requiring short length, fast opening and closing speeds, and low-pressure cutoff (small differential pressure). Butterfly valves are also suitable for two-position regulation, reduced-diameter passages, low noise levels, cavitation and vaporization, minimal atmospheric leakage, and abrasive media. They are also suitable for throttling under special operating conditions, or for applications requiring strict sealing, severe wear, or low temperatures (cryogenics).
In crude oil pipelines, butterfly valves are used to regulate crude oil flow, enabling remote automated control and improving transportation efficiency. Natural gas processing plants use butterfly valves to regulate natural gas flow and pressure to ensure smooth production operations.
