Choosing butterfly valves over any other type of control valves, such as ball valves, pinch valves, angle body valves, globe valves, angle seat piston valves, and angle body valves, has several benefits.
1.Butterfly valves are easy and fast to open.
A 90° rotation of the handle provides a complete closure or opening of the valve. Large Butterfly valves are usually equipped with a so-called gearbox, where the handwheel by gears is connected to the stem. This simplifies the operation of the valve, but at the expense of speed.
2.Butterfly valves are relatively inexpensive to build.
Butterfly valves require less material due to their design. The most economical is the wafer type that fits between two pipeline flanges. Another type, the lug wafer design, is held in place between two pipe flanges by bolts that join the two flanges and pass through holes in the valve’s outer casing. Furthermore, common Butterfly Valves materials are often less expensive.
3.Butterfly valves have less space requirements.
This is due to their compact design which requires considerably less space, compared to other valves.
4.Butterfly Valves are generally associated with reduced maintenance.
