F46 Butterfly Valve

Overview The butterfly valve uses a butterfly plate that rotates with the valve stem as the opening and closing component to achieve valve opening, closing, and flow regulation. The lined butterfly valve adopts lining technology on the flow-passing parts such as the valve body, butterfly plate, and valve stem, uniformly coating the surface with a layer of fluoroplastic. It can resist corrosion from any medium except "molten alkali metals," and has advantages such as compact size, light weight, flexible opening and closing, and easy installation. The company's butterfly valves are D71F46 and D41F46 series, featuring a split two-piece body structure. Structural Features 1. The butterfly plate of the centerline butterfly valve is concentric within the 360° circumference of the valve seat (centerline), providing bidirectional sealing and free adjustment of pressure and flow. 2. Four-stage loaded elastic sealing ensures zero leakage inside and outside the valve. 3. Simple structure, rapid switching, 90° rotation for opening and closing. 4. Flow characteristics tend to be linear, with excellent regulation performance. Design Standards Comply with GB12238, API609, MSS SP-68 standards. Actuation Methods Manual, worm gear transmission, pneumatic, electric.
