A lug butterfly valve is a quarter-turn valve that uses threaded inserts (lugs) on both sides of the valve body, allowing it to be installed between two flanges with bolts that do not pass through the valve. This design allows for easier removal of downstream piping without disturbing the other side.
Regular inspection of the disc, seat, and stem is recommended. Clean the valve periodically to prevent buildup. Check for leaks and ensure proper actuator function. Lubricate the stem if required. Replace worn seals promptly to maintain tight shut-off.
A wafer butterfly valve operates by rotating a disc 90 degrees to open or close the flow. In the open position, the disc is aligned with the flow, creating minimal resistance. When closed, the disc blocks the flow path. The resilient seat ensures tight sealing.
Ensure the pipeline is clean and free of debris. Place the valve between two flanges with bolts passing through both flanges and the valve. Tighten bolts evenly in a crisscross pattern. Do not over-tighten. Ensure proper orientation (flow direction if applicable).
The lug butterfly valve's design is similar to a 3-piece ball valve. It has threaded inserts (lugs) on both sides, allowing it to be bolted directly to pipe flanges. This enables one side of the pipeline to be disconnected without affecting the other side, making maintenance easier.
