The U flanged type butterfly valve features a compact design with shorter face-to-face dimensions compared to other valve types, saving space and weight. Its disc rotates 90 degrees to control flow, and the flange ends allow for robust, leak-proof bolted connections. Ductile iron, carbon steel, stainless steel, bronze flanged butterfly valve offers excellent sealing, simple operation, and low maintenance. The pneumatic U flanged type butterfly valve is widely used in water supply, HVAC, chemical processing, and fire protection systems for efficient shut-off and regulation duties.
