Can a butterfly valve be throttled?
Unlike gate valves, butterfly valves can be used for throttling or regulating flow as well as in the full open and fully closed position. The pressure loss through a butterfly valve is small in comparison with the gate valve.
Are butterfly valves good for isolation?
