The grooved butterfly valve features a compact design with grooved ends for quick installation using couplings, eliminating welding or threading. The ductile iron grooved butterfly valve disc rotates 90 degrees to control flow, offering low flow resistance and reliable sealing. Lightweight and cost-effective, the groove butterfly valve is ideal for applications requiring fast shut-off or modulation. Common uses include fire protection systems, HVAC, water supply, and industrial water pipelines, especially where space is limited and efficient installation is crucial.
