Key Advantages of Ductile Iron Resilient Seated Gate Valve

1.Made of high-grade ductile iron (GGG50 / QT450-10) in strict accordance with national standards. The robust, one-piece cast body delivers exceptional structural strength and impact resistance, avoiding deformation under high pressure or water hammer.

2.The resilient EPDM/NBR seat provides a bubble-tight, zero-leakage seal. It compensates for minor debris in the medium and ensures reliable shut-off even in water and sewage systems.

3.PN16 pressure rating with stable performance across municipal water supply, sewage treatment, fire protection, and industrial circulating water systems. Suitable for continuous long-term operation.

4.High-quality baking paint coating provides excellent corrosion and rust resistance. Combined with wear-resistant internal components, the valve offers low maintenance and extended service life even in buried or humid environments.

5.Standard flange drilling compliant with ISO/GB standards, ensuring perfect alignment and compatibility with most common pipeline systems. No special modification required for installation.

6.Precision-machined internal threads and stem ensure smooth, jamming-free operation with low torque. Easy to open/close manually, even after long periods of use.

7.Optimized flow path design minimizes pressure loss and reduces flow noise, delivering quiet and efficient performance even at full flow.
