The DN450 resilient seated gate valve is designed for reliable on-off control in large-diameter pipeline systems. It adopts a rubber-coated gate that ensures tight sealing performance, zero leakage, and smooth operation, making it especially suitable for water supply and water treatment applications.

The resilient seated design allows the valve to maintain excellent sealing even under low pressure or slight pipeline deformation. With a ductile iron body and corrosion-resistant epoxy coating, the DN450 resilient seated gate valve offers high strength, long service life, and stable performance in harsh working environments.

Thanks to its simple structure and low operating torque, the valve can be easily operated manually or equipped with gearboxes or electric actuators, making it suitable for both manual control and automation systems.

Advantages of DN450 resilient seated gate valve:

1. Excellent sealing performance

The rubber-coated gate provides full-contact sealing with the valve seat, ensuring zero leakage and reliable shut-off, even under low pressure conditions.

2. Long service life

The combination of ductile iron body, corrosion-resistant coating, and resilient sealing materials effectively protects the valve from corrosion, abrasion, and aging, significantly extending its service life.

3. Low operating torque

The resilient seated design reduces friction during opening and closing, allowing smooth operation and minimizing the force required, especially important for large-diameter valves like DN450.

4. Wide application range

Suitable for municipal water supply, water treatment plants, irrigation systems, and industrial pipelines, meeting the requirements of various working conditions.
