Large Span Without Intermediate Piers ：The maximum single span reaches 60 meters. No intermediate gate piers are required in the river channel, which greatly cuts civil engineering workload.
Bidirectional Water Retaining Capacity ：Capable of bearing water heads from both upstream and downstream sides.
Stepless Angle Adjustment ： The gate can stay suspended at any angle between 0° and 90°, enabling precise regulation of water level and discharge volume with flexible water dispatch.
Fast Opening & Closing Speed ：A full opening/closing cycle for single gate only takes 1–3 minutes, allowing full rapid opening for flood drainage during flood seasons.
Full-section Flow with Flat Lying Position ： When fully laid down, the gate is flush with the river bed without narrowing the flood cross-section, eliminating the risk of floating debris jamming.
Automatic Silt Flushing & Self-cleaning ： High-speed water flow during gate opening scours sediment in front of the dam automatically, eliminating regular manual dredging for long-term operation.
Outstanding Landscape Effect ：Water overflow over the upright gate forms continuous waterfalls, which can be combined with lighting to build urban waterfront leisure water landscape projects.
Durable All-steel Structure ：Made of high-strength weather-resistant steel plates with multi-layer anti-corrosion treatment, with a design service life of 30 to 50 years.
Intelligent Multi-mode Control ：Supports local manual operation, remote electric control and automatic water level linkage, realizing unattended operation.
Unobstructed Navigation ：No protruding dam body under full open status, which will not block small vessels and satisfy river navigation requirements.
