This DN200 ductile iron soft seated flanged gate valve is designed for stable shutoff performance and long-term operation in municipal and industrial pipeline systems. Made from high-strength ductile cast iron, the body delivers excellent mechanical performance and impact resistance while ensuring low deformation even under long-term pipeline pressure. The resilient soft seated structure provides low leakage and tight sealing, making it suitable for clean water, sewage transportation, urban drainage networks and industrial water treatment systems.

The valve is equipped with a wedge-type gate that moves linearly along the pipeline axis to complete full opening and closing, minimizing flow resistance and ensuring smooth medium passage. Compared with butterfly or ball valves, this structure reduces energy loss and is particularly suitable for large-diameter municipal supply systems and long pipeline installations. The internal rubber-coated sealing surface also prevents seat wear, reducing maintenance frequency and extending service life.

The flanged connection design ensures high installation stability and supports pressure ratings such as PN10, PN16 and PN25, meeting requirements for city water supply, rural irrigation, fire protection systems and mechanical equipment pipelines. The valve is compatible with manual handwheel operation, worm-gear transmission and electric actuation, enabling flexible deployment based on project automation needs. Depending on project standards, the product can be supplied according to DIN, ISO, BS or AWWA specifications for seamless procurement in international engineering markets.

Its corrosion-resistant coating further enhances durability by protecting the valve body from moisture, soil, outdoor exposure and chemical condensation in underground installations. With reliable sealing performance, low torque operation and wide applicability, this gate valve is widely used in municipal water supply, sewage treatment plants, agricultural water conservancy, infrastructure construction, power projects and public utility pipeline systems as a dependable shutoff solution for long-term stable operation.
