Product Details
U type butterfly valves are widely used quarter‑turn rotary valves in fluid control systems. Featuring a simple, compact structure, they effectively realize flow regulation and reliable shut‑off. The working principle is straightforward: the disc rotates 90° within the valve body. When open, it aligns parallel to the flow direction for low resistance; when closed, it stands perpendicular to achieve tight sealing and prevent leakage. This valve is equipped with a manual lever as standard. It can also be fitted with a worm gear operator, pneumatic actuator, or electric actuator to satisfy the control requirements of various working conditions.
kefa manufacture ductile iron DN1000 butterfly valve to EN593 standards—the European specification for water supply and general purpose butterfly valves. The robust flanged body and precision U-section disc profile provide optimized flow characteristics and reduced turbulence, ensuring efficient mainline isolation.
As the manufacturer, KEFA produce this valve in our dedicated large-diameter facility. From casting and coating to final assembly, every step is controlled in-house. Each DN1000 unit undergoes full hydrostatic shell and seat testing per EN12266 (or equivalent) before shipment, with test reports provided. The robust, infrastructure-grade solution for water treatment plants, reservoir outlets, and transmission mains. Available with custom coatings, actuation, or bypass arrangements.
