Experımental analysıs of the performance coefficients of the butterfly valves [PDF]
, 2009 In the present work, two different butterfly valves, DN65 and DN80, were tested according to standard testing method ANSI/ISA-75.02-1996. The tests were performed at different flow rates such as 2, 3 and 4 m/s and at different valve opening angles such as 0, 10, 20, 30 and 40°. The opening angle 0° was considered as the fully open valve.
