Lug butterfly valve manufacturer in India

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, Pharmaceutical 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.

Below are some of the standards of Butterfly valve

• DIN
• JIS
• BS
• ANSI
• API
• ASME
• AWWA

Advantages of Lug Butterfly valves

• They are suitable as end valve.
• They are easier to center
• They are less sensitive in case of large temperature differences.

   Lug 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.
