An Industrial Gate, also referred to as a Sluice Gate or Flap Gate, is a critical flow control device used to regulate, isolate, or stop the flow of water, wastewater, slurry, or other non-compressible fluids in open channels or pipelines.
Commonly made from stainless steel, carbon steel, or cast iron, these gates are widely used in water treatment plants, irrigation systems, flood control systems, sewage treatment plants, and industrial process water management.
| Gate Type | Application & Features |
| Sluice Gate | Vertically lifting gate used in open channels, often motor/manual operated |
| Flap Gate | Non-return gate that opens with flow pressure and prevents backflow |
| Slide Gate | Linear movement for quick shut-off in pipelines or ducts |
| Weir Gate | Overflow-type gate for level regulation in reservoirs, ponds, etc. |
| Knife Gate | Used in slurry/sewage applications to cut through solids |
| Material Options | Features |
| Stainless Steel (304/316) | Corrosion-resistant, ideal for wastewater & food industry |
| Carbon Steel (Epoxy Coated) | Cost-effective, suitable for municipal & irrigation |
| Cast Iron / Ductile Iron | High strength, large-scale waterworks and dam systems |
Key Advantages of Gate (Sluice Gate) Over Gate Valve
* Can be installed in open channels, pits, tanks or weirs to regulate or shut off water flow without pressure.
* Simple structure and easy operation, ideal for stormwater, sewage inflow/outflow regulation, or overflow control.
* Supports extra-large size customization (DN1000 and above), while gate valves are typically limited by casting & pressure specs.
* Wall-mounted or embedded options can be integrated directly into concrete/civil works – saving space and cost.
* Better suited for dirty fluids with debris, such as rainwater, wastewater, irrigation flow – less prone to jamming.
