How to select a butterfly valve?

1. Because the pressure loss of butterfly valves is relatively greater compared to gate valves and ball valves, they are suitable for pipeline systems where pressure loss is not a strict requirement.

2. Since butterfly valves can be used for flow regulation, they are appropriate for pipelines that require flow adjustment.

3. Due to the structural limitations and sealing materials of butterfly valves, they are not suitable for high-temperature and high-pressure pipeline systems. Generally, the working temperature is below 300 degrees, and the nominal pressure is below PN40.
