LUG BUTTERFLY VALVE SUPPLIER IN INDIA 

Speciality Valve has established itself as a top-rated Butterfly Valve Supplier in India, providing rugged valves that meet performance, cost, and minimal design requirements for thousands of applications. When a pipeline requires quick, dependable flow control without cumbersome hardware, butterfly valves are the way to go. 

Meaning: Butterfly Valve 

A butterfly valve is a quarter-turn valve that employs a round disc supported on an axial shaft to control flow. Rotation of the shaft positions the disc parallel (open) or perpendicular (closed) to the fluid flow, allowing for quick shut-off and low pressure drop. 

What is a Lug Butterfly Valve? 

A lug butterfly valve has threaded metal “lugs” along its body. These permit the valve to be bolted between flanges on each side of the piping, so downstream piping can be removed without disrupting the upstream side—perfect for applications requiring simple maintenance or sectional isolation. 

Why Required? 

Butterfly valves are essential where room, weight, and cost need to be reduced without sacrificing tight shut-off or moderate throttling. They are the industries’ preference for big-line sizes, corrosive fluids, and frequent operation applications where gate or globe valves would be cumbersome. 

Key Components of Butterfly Valve 

• Valve Body: cast iron, ductile iron, stainless, or alloy steel 

• Disc: corrosion-resistant metal or high-performance composite 

• Shaft/Stem: conveys torque from actuator or handle to disc 

• Seat/Liner: elastomer or PTFE for bubble-tight sealing 

• Bearings & Bushings: minimize wear and friction 

• Actuator/Handle: manual gear, lever, pneumatic, or electric 

Working Mechanism 

A 90-degree shaft rotation rotates the disc. The disc is parallel to flow in the open position for minimum interference; in the closed position, it blocks off against the seat to prevent flow. Lug connections enable the valve to carry pipeline weight from either side for maintenance. 

Advantages of Butterfly Valve 

• Space-conserving and light 

• Reliably quick quarter-turn action 

• Low pressure drops 

• Economical in large sizes 

• Easy to install and maintain 

Functions of Butterfly Valve 

• Isolation on/off
