It is a special gate valve designed for precise adjustment of water level and flow, divided into series such as bottom - opening type, top - hinged type, and rotary type. The height of the weir gate 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, and landscape water bodies.

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

Key Features
Modular Assembly: Composed of multiple stop log segments assembled vertically, opened and closed via layered hoisting without requiring large-scale hoisting equipment.
Lightweight Structure: Simple structure with light individual beams, allowing for flexible handling, disassembly, and assembly.
Reliable Sealing: Relies on self-weight to compress seals, ensuring dependable sealing performance. The water blocking height can be adjusted segment by segment.
Durable Materials: Primarily constructed from Cast Iron, Carbon Steel, or Stainless Steel, offering wear resistance and corrosion protection.
Non-Mechanical: Features no complex transmission parts, suitable for temporary sealing and segmented water blocking.
Typical Applications
Water Conservancy: Temporary water blocking and maintenance isolation for channels, small culverts, sluices, and water intakes.
Municipal Facilities: Maintenance sealing for tanks, manholes, and corridors in water treatment and sewage treatment plants.
Irrigation & Drainage: Temporary flow control and cofferdam cut-off for irrigation districts, drainage ditches, and small-to-medium rivers.
Advantages
Cost-Effective: Low manufacturing cost with no need for large hoists, minimizing both civil and equipment investment.
Easy Deployment: Quick disassembly and assembly enable rapid temporary sealing, facilitating convenient maintenance operations.
Adjustable Height: Flexible water blocking height; simply add or remove segments as required.
Reusable & Compact: Requires minimal storage space and is reusable, offering high economic efficiency.
Wide Applicability: Ideal for short-term water retention and maintenance isolation scenarios.
