Flange Non-rising Stem Hard Seal Gate Valve

Size range: 2"-12" (DN50-DN300)   Design standard: BS EN 1171   Connection standard: EN 1092-2   Working pressure: PN16, PN10

Product description
This valve is mainly used to connect and cut off the medium in pipelines. The valve stem rotates, and its transmission thread is inside the body cavity, which can save installation space. The sealing surface is made of high-strength copper alloy, ensuring reliable sealing and long service life.
Customer challenge
The opening and closing torque of the gate valve is large.
The upper seal and middle flange of the gate valve are prone to external leakage.
Insufficient machining accuracy is prone to internal leakage.
Product function
Low operating torque function
Anti-external leakage function
Anti-internal leakage function
The valve can be easily closed with a torque of 80% of the nominal diameter (DN), achieving zero leakage under nominal pressure.
The upper seal adopts a multi-packing design to ensure no water leakage during the dynamic movement of the valve stem; the middle flange features a self-sealing design, where the greater the pressure in the valve chamber, the tighter the extrusion, and the more reliable the sealing.
Processed and produced by special equipment, the sealing surface has high machining accuracy, ensuring reliable sealing and no internal leakage.
Value advantage
  •  Energy conservation and environmental protection
    Energy conservation and environmental protection
    The surface is treated with non-toxic epoxy resin powder, which is sprayed by an automatic powder coating line to ensure uniform and continuous coating thickness.
  • Excellent Material Quality
    Excellent Material Quality
    All ductile iron castings are self-cast using domestically leading wire-feeding nodulization technology, with a nodularity rate exceeding 90%. The quality requirements are higher than national standards.
  • Low Flow Loss
    Low Flow Loss
    Full-passage design results in low flow loss, achieving energy saving and consumption reduction.
  • Low Torque
    Low Torque
    Under rated working pressure, the opening and closing torque is no higher than 80% of the requirements specified in national standards.
  •  Reliable Sealing
    Reliable Sealing
    Processed and produced by special equipment, the sealing surface features high machining accuracy, ensuring reliable sealing and no internal leakage.
