Product Introduction: 

Large-diameter resilient-seated gate valves are optimized and strengthened based on the standard resilient-seated gate valve structure, 

specifically developed for high-flow-rate main pipelines such as municipal trunk lines, water plant inlets and outlets, and large sewage pipelines. 

Standard diameters range from DN500 to DN1200.

Featuring a thickened ductile iron valve body and a fully encapsulated EPDM rubber gate, it achieves bidirectional bubble-level zero leakage. 

Unlike older large-diameter hard-seal gate valves, it is less prone to sand accumulation and has lower opening and closing torque, 

making it the mainstream choice for urban water supply trunk pipelines.

Main Features:

1.Reinforced ductile iron QT450 body with fusion bonded epoxy coating, anti-water hammer, corrosion resistant for potable water.

2.Fully EPDM rubber wrapped wedge, bi-directional bubble tight zero leakage.

3.Full bore flat bottom design, no sediment accumulation, available for pipeline pigging.

4.Bevel gear operator for DN600 and above, low operating torque; electric actuator optional for remote automatic control.

5.Non-rising stem for underground valve chamber; rising stem version optional for pump room.
