Ductile iron casting delivers high strength, lightweight portability, and dimensional accuracy, ensuring reliable foundation sealing.
01
The gate plate features integral rubber lining with vulcanized bonding, offering excellent elasticity, resistance to aging, zero leakage, and compatibility with diverse media.
02
Internal threaded connections comply with common standards, enabling simple installation, reliable sealing, and suitability for confined spaces and pipeline retrofits.
03
Flat-bottomed valve seats prevent sediment buildup, copper nuts resist loosening, epoxy coatings combat corrosion, and support for both exposed and concealed stems ensures adaptability across diverse applications.
04
Ductile iron threaded soft-seal gate valves utilize the linear motion of a wedge-shaped gate plate to control media flow: When opening, rotating the handwheel clockwise engages the threaded connection between the valve stem and bronze nut, driving the gate plate to move vertically upward along the seat. This action fully disengages the gate plate from the sealing surface, ensuring unobstructed media passage. To close, rotate the handwheel counterclockwise. The gate moves vertically downward, tightly sealing the rubber face against the seat. The medium's own pressure enhances sealing effectiveness, achieving reliable flow interruption. The soft-seal design significantly reduces operating torque, enabling light and flexible operation ideal for applications requiring frequent cycling.
