Allied Valves India is a leading Lug Type Butterfly Valve Manufacturer and Supplier in India. We supply versatile, dead-end service butterfly valves to process industries across India.

What is a Lug Type Butterfly Valve?

A Lug Type Butterfly Valve is a versatile flow control valve fitted with threaded lugs on its body, allowing it to be bolted into a pipeline independently on either side — suitable for dead-end service where downstream piping can be removed without affecting the valve. Available in Cast Iron, Cast Steel, SS 304, SS 316, and Ductile Iron body options, with pressure ratings up to PN 25, built for sizes 15mm to 300mm.

Applications of Lug Type Butterfly Valve

Suited for dead-end service or single-sided pipe isolation, including water treatment and process piping where flexibility to remove downstream sections is valuable.

Benefits of Lug Type Butterfly Valve

• Threaded lugs allow bolting from either side independently
• Supports dead-end service, unlike standard wafer-type valves
• Broad body and disc material options suit varied conditions
• Multiple seat/seal choices allow chemical compatibility
• Lever and gear operation options suit different control needs

Working of Lug Type Butterfly Valve

The valve’s disc rotates on a central stem within the lugged body to control flow. In the open position, the disc aligns with the pipe bore for minimal flow resistance. To close, the disc rotates a quarter-turn, sealing firmly against the replaceable seat. Because the body has threaded lugs instead of through-bolts, either side of the pipeline can be unbolted and removed for maintenance while the valve stays securely fixed to the other side — a key advantage over standard wafer-type designs.
