Description: Butterfly valves are the most specified valve type for moderate-duty conditions in pipe sizes of two inches and larger. Their reduced weight, reliable bubble-tight shut-off, ease of operation and automation allowed them to displace gate valves in traditional applications. Bi-directions shut-off is one of the hallmarks of butterfly valves. Continuing development of the butterfly valve is making it possible to use them in aggressive applications that previously were the exclusive domain of gate and globe valves.
