Wafer butterfly valves are typically sandwiched between two flanges using bolts and nuts. The pressure of the nuts on the backside of the flange holds the valve in place. Wafer butterfly valves are the more common of the two designs of butterfly valves, the other design being lug style. Wafer butterfly valves are easier to install and cheaper than the lug style.
Wafer butterfly valves can be made of a variety of materials, including stainless steel, plastic, and other metals. Although plastic is cheaper, it is not used as often because it is more prone to corrosion than metals. Aluminum is also occasionally incorporated to make the gasket part of the valve, since it is a lightweight and flexible metal.
