When We Choose A Butterfly Valve?
1. Due to the relatively large pressure loss of butterfly valves compared to gate valves and ball valves, they are suitable for pipeline systems with less stringent pressure loss requirements.
2. As butterfly valves can be used for flow regulation, they are suitable for use in pipelines that require flow regulation.
Due to the limitations of the structure and sealing materials of butterfly valves, they are not suitable for use in high-temperature and high-pressure pipeline systems. The general working temperature is below 300 ¡æ, and the nominal pressure is below PN40.
4. Due to the short length of the butterfly valve structure and its ability to be made into large caliber valves, butterfly valves should be selected in situations where the structural length is required to be short or for large caliber valves (such as DN1000 or above).
5. Due to the fact that butterfly valves can be opened or closed by only rotating 90 °, it is advisable to choose butterfly valves in areas with fast opening and closing requirements.
