Lug butterfly valve manufacturers in India

Speciality Valve is a trusted Lug butterfly valve manufacturers in India specializing in precision-engineered valves for industrial applications. Our high-performance lug-type butterfly valves are engineered with utmost priority to performance, reliability, and installation ease, making them ideal for both control and isolation of flow.

Why Required?

Lug-type butterfly valves are necessary for piping systems when the valve must be removed without affecting the line as a whole. Their threaded lug design permits them to mount and demount separately from either side of the pipeline, thus they are suited for dead-end service and high-maintenance applications.

Key Components of Lug Butterfly Valve:

Body: Lugged with threaded inserts for quick mounting

Disc: Normally constructed of stainless steel, ductile iron, or other materials resistant to corrosion

Seat: Metal-seated or soft shut-off close

Stem: Retains disc to actuator

Actuator: In current forms like manual, pneumatic, or electrical

Working of Lug Butterfly Valve:

The lug type butterfly valve operates by turning a disc in the direction of flow. The lugs on the valve body screw into bolt holes in the pipeline flanges, and the valve is bolted in place. The actuator turns to rotate the disc 90° to close or open the flow. This design makes it possible to shear off one side of the pipeline without influencing the other.
