Structural Characteristics of

• The body is cast from QT450-10 high-strength ductile iron, offering elongation and tensile strength far superior to gray iron. This allows the valve to absorb stress during pressure surges or water hammer in municipal water networks, preventing brittle fracture and ensuring the structural integrity of the pipeline.

• The top-mounted multi-turn electric actuator integrates advanced control modules supporting remote PLC or DCS commands. Operators can precisely monitor the valve position from a central control room without site visits, making it perfect for unmanned pump stations or large-scale industrial process automation.

• The robust wedge gate structure generates strong mechanical sealing pressure during closure. Combined with the actuator’s high torque output, the valve achieves zero-leakage shut-off even under high differential pressure, acting as a highly reliable main isolation valve for long-distance transmission pipelines.

• Both internal and external surfaces are treated with electrostatic epoxy powder coating, creating a dense protective barrier. This prevents corrosion from soil or media and meets drinking water hygiene standards, avoiding secondary contamination and extending the valve’s service life in harsh buried environments.

• The actuator features an independent manual handwheel and declutch lever, allowing technicians to quickly switch to manual mode during power failures or commissioning. The handwheel is easy to operate, ensuring the valve can be safely opened or closed in extreme emergencies, providing a final safety barrier for flood control systems.
