Butterfly Valves are intended to control flow, however their
control methods are limited. By rotating a handle 90 degrees, butterfly valves
can be opened and closed. It consist of a metal disc in the valve's body that
is parallel to the surface facing the flow when it is closed. The flow of
liquid is controlled by alternate rotations.

Difference between Wafer butterfly valve and Lug
butterfly valve
Wafer butterfly valve the
body is annular with a few non-tapped centring holes, and it's a Wafer-style
butterfly valve. There are two sorts of Wafers, and there are four types.
The flange bolts are placed into the centering holes
of the butterfly valve and the bolt holes of the two pipe flanges. The pipe
flanges are brought together by tightening the flange bolts, and the butterfly
valve is clamped between the flanges.
Lug butterfly valve
there are so-called "ears" around the whole circle of the body of a
Lug-style butterfly valve into which threads were tapped. The butterfly valve
can then be tightened against each of the two pipe flanges using two separate
bolts in this manner (one on each side).
The probability of relaxation due to thermal
expansion is lower than with a Wafer-style valve since the butterfly valve is
fastened to each flange on both sides with separate, shorter bolts. As a
result, the Lug version is more suited to applications with significant
temperature variations.
