It is a special gate designed for precise adjustment of water level and flow, divided into series such as bottom - opening type, top - hinged type, and rotary type. The weir height is adjusted by the hoisting mechanism to accurately control the overflow water level and through flow. It operates smoothly with high adjustment precision, and is widely used for the refined regulation of aeration tanks, sedimentation tanks in sewage treatment plants, filter tanks in tap water plants, landscape water bodies, etc.  

This product is a non-standard customized item, with dimensions and pressure ratings based on actual customization requirements.

Key Features
Precise Water Level Control: The weir plate raises and lowers to accurately control the weir crest elevation and overflow height.
Bottom-Opening Design: Opens downward or rotates on an axis, occupying no overhead space, making it ideal for installation on tank roofs or within channels.
Superior Sealing: Features three-sided sealing with rubber or embedded bronze, ensuring zero leakage and supporting bi-directional water stoppage.
Lightweight Structure: Approximately 2/3 lighter than conventional sluice gates, requiring smaller actuators (electric/hydraulic) and allowing for easy installation.
Durable Materials: Constructed from Cast Iron / Carbon Steel / Stainless Steel, offering corrosion and abrasion resistance, suitable for sewage and sediment-laden water flows.
Typical Applications
Municipal WWTPs: Water level and flow regulation in oxidation ditches, distribution wells, sedimentation tanks, and effluent weirs.
CSO (Combined Sewer Overflow): Used in interception wells, box culverts, and channels for dry weather flow interception and wet weather overflow switching.
Water Supply & Drainage: Water level control for outlet channels of clear water reservoirs, retention basins, and pump stations.
Water Conservancy & Landscape: Water level regulation for small channels, culverts, sluices, and landscape water systems.
Advantages
Accurate Level Control: Fine-tuning of overflow ensures process stability and high-quality effluent.
Space-Saving: The bottom-opening design eliminates the need for tall hoist structures, significantly reducing civil engineering costs.
Strong Backflow Prevention: Bi-directional sealing effectively prevents external water backflow.
Simple O&M: Compact structure with a low failure rate, easy seal replacement, and support for remote automatic control.
Wide Applicability: Suitable for clear water, sewage, and industrial wastewater; available in widths up to 5m+.
