The austenitic stainless steel grades are the most used ones where high alloy valves are used for special purpose applications. The Flanged Wafer Butterfly Valves avoid water hammer effect by being inside the fluid flow all the time. The valves can also be of different sizes and dimensions with pressure differences. The valve size ranges from 2 inches to 48 inches and the pressure capacities range from 150lbs to 2500lbs. The Double Flanged Concentric Butterfly Valves are used in water, oil and gas, waste water and in other fluid control systems as well. The eccentric valves have eccentric type of discs as gates where the concentric types have concentric shaped gate discs.
