Double-flanged butterfly valves have a pair of flanges constructed on each facet of the valve body; these match the dimensions of the pipe flanges. Two sets of bolts and nuts are used to help the valve on each side; this produces a strong attachment. Double-flanged check valvewafer butterfly valve valves are more common in butterfly valves with larger sizing.
