Bonneted Gates

Bonneted gates are normally used for regulating flow in dam outlet works and remove silt through flushing tunnel. It is a completely enclosed slide gate that is designed and manufactured to be embedded (except for the actuator) in concrete. These gates are used for high water head application and extreme abrasive environment.

A Bonneted Gate consists of a vertically sliding disc, bonnet body, bonnet, bonnet cover, upstream and downstream transition sections, one or more conduit Liner sections, and an actuator. Bonneted gates are often supplied with paired gates and both upstream and downstream transition sections. This entire assembly is often embedded in the primary concrete pour deep in the dam. While this provides unsurpassed structural support, it makes gate replacement impossible. From a practical perspective, only the slide can be serviced without extraordinary efforts.

These gates are offered in various materials of construction such as Stainless steel / Super Duplex stainless steel / Structural steel etc. to suit the intended application. These gates can be operated with electric and hydraulic operating systems.
