Installs in duct inlets and outlets of funds under high loads, where the speed of passage through the ducts are very high. A gate installed in these ducts BUREAU produce cavitation effects and significant disturbances in the side holes and even severe depression in the housing chambers. With this type of gate (ring-follower) does not produce these effects.
It comprises a reinforced frame forming a box, within this framework there is a sliding panel that performs the function of shutter. The board at its bottom has a hole diameter of the duct. When the board is still down, water will remain blocked. When the board goes up, providing continuity in the pipeline, ensuring regular shock undisturbed. This board is powered by a hydraulic cylinder, which performs the function of opening and closing. The seats and the guides are metal and are designed for longer life and maintenance free. However, the lower chamber requires to be provided with a pipe cleaning sludge, grit and other sediments.
It should install a bypass system and a vent for easy operation.
This type of door should not be used as a regulator.
