The gate for high water level and large sections.
- Description: The roller gate allows to regulate or cut the flow, rollers on each side can facilitate the operation.
- Application : For security in a penstock, high hydrostatic pressure...
- Safety : It is possible to have gravity closing or opening that do not require energy input.
- Operation : hydraulic cylinder of a screw/gearmotor system.
- Description : It is used for moderate frequency applications and for relatively small dimensions and loads (as gravel slide gate...)
- Application : Can be adapted as a safety gate.
A flapper can be install on the gate for flow regulation or upstream water level regulation.
- Description : a stoplog is a temporary gate designed to isolate a submerged part to dry a downstream or a upstream area in order to carry out contrsution work or maintenance on the hydraulic equipment..
- Application : it can be install upstream or downstream of a gate into groove section to isolate the gate from upstream and downstream water level, it can be design as one part or as many stackable element.
- Operation : can be operated under zero load by chain or lifting beam, under light loads by manual fixed jacks, under heavy load by hydraulic cylinders of electrical jacks.
