STAINLESS STEEL Aluminum Lever Lug Style Fire Water Butterfly Valve

The stainless steel aluminum lever lug style fire water butterfly valve operates by rotating a circular disc mounted on a central shaft to control water flow. When the aluminum lever is turned a quarter turn, the shaft rotates the disc from a closed position, where it seals tightly against the resilient seat, to an open position aligned with the pipeline. This simple rotary motion allows rapid opening and closing, which is critical for fire protection systems. The lug-style body enables secure bolting on both sides of the pipeline, providing strong end-line service capability. Stainless steel construction ensures corrosion resistance, while the lever mechanism allows manual, reliable operation without external power, ensuring dependable performance during emergency fire water distribution.
