Specialityvalve is a leading Wafer Butterfly valve manufacturer in India. A Wafer Butterfly Valve is manufactured with four holes that align with the connected pipeline. It is easy to be installed but cannot be used as an isolation valve. 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. Industries like Oil and Gas, Chemical Processing, water and wastewater processing, Food processing, and manufacturing use Wafer Butterfly Valve.

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.
Below are some of the standards of Butterfly valve
• DIN
• JIS
• BS
• ANSI
• API
• ASME
• AWWA

Advantages of Wafer Butterfly valves
• They are lighter in weight.
• It is cheaper.
• It is easy to installed
Wafer Butterfly is widely used in a variety of Industries, including
• Oil and Gas
• Chemical Processing
• Water and Wastewater processing and transportation
• Food Processing

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.
