Detailed introduction:
Ductile iron flange butterfly valves are commonly used valves; here's an introduction to them:
Structural Components: Consists of a ductile iron valve body, butterfly disc, stem, sealing rings, and more, and can be equipped with manual, electric, pneumatic, or other types of actuators.
How it works: By driving the valve stem, the butterfly disc rotates 0–90°, enabling the valve to open or close, or to regulate flow.
Performance parameters: Nominal diameter DN40–DN1200, nominal pressure PN1.0–PN2.5. When using soft seals, the applicable temperature range is typically 0–180°C.
Product features: The ductile iron valve body boasts high strength and lightweight design, with a simple and compact structure, requiring minimal operating torque. It offers quick 90° rotation for rapid on/off operation, excellent flow characteristics, and features replaceable seals for reliable bidirectional sealing—plus, it can be installed in any position.
Application areas: Suitable for industries such as water supply and drainage, food processing, and heating, where temperatures are ≤120℃ or ≤150℃ and nominal pressures are ≤1.6 MPa. It can handle media like water, air, oil, and more.
