Integral Flat Structure: Adopts straight flat gate leaf design with neat and compact overall structure.
Two Sealing Options Available :Two sealing types optional: rubber soft sealing and copper-lined hard sealing. Customers may select freely based on water head height and water quality working conditions.
Tight Water Sealing Performance: High fitting precision between gate leaf and frame with tiny fitting clearance. Excellent anti-seepage effect after full closure to completely eliminate water leakage through gaps.
Effortless Opening & Closing: Uniform stress distribution on flat panel with no lateral resistance during lifting and lowering. Smooth vertical movement, requiring minimal labor force even for manual operation.


Strong Resistance to Water Flow Impact: Sufficient rigidity of the gate plate to withstand direct frontal water impact. No shaking or displacement during operation for superior stability.
Robust & Durable Material: Integrally cast from high-quality cast iron featuring high overall hardness, strong compression and deformation resistance. No bulging or deformation under long-term water pressure.
Anti-Corrosion & Anti-Aging Treatment: Professional anti-corrosion coating applied on surface. Resistant to sewage corrosion and humid environments, free from rust after long-term service in river channels and wastewater treatment plants.
Bidirectional Pressure-Bearing Structure: Engineered for high bidirectional water head bearing with rational concentrated force distribution, maximizing sealing and pressure resistance performance.
Effective Backflow Prevention: Tight sealing upon full closure blocks backflow from downstream, widely applied to pipeline outlet anti-reflux projects.
Wide Range of Application Scenarios :Suitable for farmland irrigation channels, municipal culverts, wastewater treatment plants, small reservoirs, municipal water supply & drainage and other hydraulic projects.
Ultra-Long Service Life :Wear-resistant, pressure-proof, anti-corrosion and anti-scour. Low maintenance frequency under normal operating conditions with a service life of over 50 years.
