Fabricated Slide Weir Gates for Wastewater Solutions Flow Control - Penstocks and Rollergates


For controlling the water level on one side of a gate, weir gates are used and are features with a downward opening which allows the water flow over the top of the slide. Dutco Tennant LLC is a reputed supplier fabricated slide gates that have been designed and manufactured with custom extrusions, structural members, and brake-formed plates. Aiding with our years' experience, we along with our suppliers have developed techniques for fabricating high-quality slide gates that have been designed and built for specific projects. As there is an absence of machined parts or wedging devices, the gate depends upon seal design to seal fabricated slide. The Fabricated slide gates are furnished with UHMW seals which is a highly effective and proven design. They are designed for either open channel use or aperture type applications.

In several treatment plants, there is a requirement of downward opening fabricated gates to permit a rough measurement of flow or to maintain a constant upstream water elevation. For these installations, the gate slide opens downward for allowing the flow of water over the top of the slide or weir plate. Either manual or electrically actuated lifting devices can be utilized for this. Weir gates may or may not be self-contained.

Unique Features –
  • Premium Self-Adjusting Seals
  • The side and top seals are self-adjusting to ensure long term tight sealing and they are constructed of UHMWPE (Ultra-High Molecular Weight Polyethylene) with a nitrile compression cord.

  • Thoroughly Tested Several Times
  • The weir gates that we supply are made to pass through several tests before they leave our facility.

  • Zero Maintenance Cost
  • The valves which we supply have a self-adjusting design which eliminates any requirement for maintenance. Seals have no metal-to-metal contact to ensure no sticking, even after years of non-operation.
