  • The term ‘Sluice Gate’ is no longer recognized by AWWA
    • GH considers a heavy-duty fully wedged gate a ‘Sluice Gate’
  • Typical use:
    • Isolation (Open/Close)
    • Flow monitoring via covering or partially an opening or orifice (Throttling Service)
  • Incorporates a horizontal top seal
  •   Reference Models: GH-27 (AL), GH-29 (S-Stl) & GH-100 (S-Stl)
  • Provides Superior Sealing Performance. Up to 1/100th of that allowed per AWWA Standards.

Open Top Slide/Sluice Gates

Upward Opening
  • Typically use Isolation (open/close) service.
  • Similar to the submerged service gate, water sluices under the slide
  • In channel or embedded or surface mounted to the end of channel
  • Can be face mounted to cover opening/orifice when water level is low

Weir Gates

Downward opening
  • Typical use Upstream level control or flow monitoring (Modulating service)
  • Water cascade over the gate as the slide is opened downward.
  • Design consideration: Must design a drop below the gate for full downward  travel

Self Contained Frame

In this design, the gate frame supports the slide and the actuator

Non-Self Contained Frame

Only slide is supported by frame

The gate frame only support the slide. A pedestal or wall bracket support the actuator.
