1. Suitable for making valves with larger diameters (such as DN600 and above)
2. Butterfly valves are suitable for fields with short structural length requirements
3. Not suitable for high-temperature and high-pressure pipeline systems, generally used for media such as crude oil, oil products, water, etc. with temperatures ≤ 80 degrees and pressures ≤ 1.0Mpa.
4. Due to the relatively large pressure loss of butterfly valves compared to gate valves and ball valves, butterfly valves are suitable for pipeline systems with less stringent pressure loss requirements
5. It is suitable to choose in pipelines that require flow regulation
6. Butterfly valves are suitable for situations where quick opening and closing are required
7. Usually, in throttling control and mud media, it is required to have a short structural length, fast opening and closing speed, and low pressure cutoff (small pressure difference). Butterfly valves are recommended to be used
8. Butterfly valves can be selected for dual position adjustment, channels with reduced opening, low noise, gasification phenomenon, slight leakage to the atmosphere, and corrosive media.
When using butterfly valves under special conditions such as throttling regulation, strict sealing requirements, severe wear, and low temperature (deep cold), special metal sealed regulating devices with three or double eccentricities should be used.
