Specialityvalve is the
greatest Lug butterfly
valve manufacturer in India. Lug
butterfly valve has eight lugs attached to the body of the valve. Butterfly
valves are used to stop, regulate and start the flow of the medium. They are
easy and fast to open. Large butterfly valves comes with a gear box where the
handwheel by gears is connected to the stem. In this type of valve, a disc is
attached to the rod. That disc allows the fluid to flow through the valve. The
main components of butterfly valve are the body, disc, stem, and seal. The work
of the butterfly valve is like that of a ball valve. It is used in various
industries like chemical industry, food processing industry, and they are also
used in steam services, fire services and water treatment plants.
What is butterfly valve?
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.
