Butterfly valve is suitable for regulating flow. What are the suitable occasions for it?

It is generally used to adjust the flow rate of large-caliber fluid. Generally, the leakage level is not too high, and it is suitable for occasions where the leakage amount is not too high and the maximum allowable pressure difference is not too high (medium and low pressure systems). Although its flow characteristics are approximately equal percentage, it is not suitable for working in large openings and small openings (both ends) (poor characteristics).

It is often used to adjust the flow rate of medium and low pressure and large caliber gas or liquid.
