What are the characteristics of pneumatic butterfly valve? Where is it used?
1) The leakage flow is small, because there is only one valve element, it is easy to ensure the sealing. The standard discharge flow is 0.01% KV, and further design can be used as a pneumatic butterfly valve.
2) Due to the unbalanced force, the allowable pressure difference is small and the thrust is large. DN100 valve △ P is only 120KPa.
3) The circulation amount is small. The KV of DN100 is only 120. It is usually used in situations with little leakage and small pressure difference.
