Electric soft seal gate valve
The top-mounted design of this electric soft-seated gate valve reduces stress on the connecting bolts of the valve body, improving reliability and helping maintain normal operation despite the system’s weight. It addresses common gate-valve issues such as poor sealing, elastic fatigue, and corrosion by using the elastic compensation effect of the gate plate to achieve effective sealing through controlled deformation. Key advantages include light operation, reliable sealing, good elastic memory,
Electric Soft-Seal Gate Valve

Product Advantages
- QT450-10 ductile iron body, 3-level spheroidization rate. Tensile strength: 450 MPa. Elongation: over 10%. Not prone to cracking or freeze cracking.
- Epoxy coating on both the inside and outside of the valve. Coating thickness: over 250 μm. Effectively helps prevent corrosion and rust of the valve body. Suitable for sewage systems.
- EPDM-coated ductile iron wedge with 50% rubber content. The rubber is firmly bonded to the wedge, helping to prevent peeling.
- 2Cr13 valve stem. Three O-ring sealing design. Reduces frictional resistance during operation and minimizes medium exposure.
- Brass stem nut and positioning device for smoother switching and to help avoid jamming during operation.
- IP65 protection rating electric actuator.
