A butterfly valve are not used for fluids containing solid particles however while they could prevent it from closing completely.

The butterfly valve is usually a quarter-turn valve. It requires a 90° rotation between open and closed position to control. For large diameters, it could require an actuating system designed with a gearbox that compensates for that pressure exerted on the valve.

Butterfly valves are meant to ensure a fantastic sealing system. Large diameter butterfly valves often use flange mounting, and the ones intended for heating circuits, as an example, are likely to be screw-in valves. Butterfly valves ordinarily have a minimal space requirement, especially as compared to ball valves.

The flexible wedge can be one-piece construction just like a solid wedge, but areas behind the seating surfaces are empty to provide flexibility. This construction compensates for alterations in seat alignment for improved seating whilst the strength of a compelling wedge inside middle. This design offers better leak tightness and improved performance in situations with possibility of thermal binding.

The split wedge includes two-piece construction which seats between tapered seats from the valve body. The two components of split wedge seat flat from the valve seats as being the stem is moved downward, and in addition they move away from the valve seats in the event the stem is pulled upward.
