Manual three-side sealing sluice gate

The three-side sealing sluice gate with manual actuation has the function of intercepting and/or deviating a water flow in a channel or a basin. This operation is ensured by the opening or closing of a pad actuated manually by a handwheel. The sluice gate is fixed to the wall of the channels, usually made of reinforced concrete, finished so as to not exhibit any projecting bumps that could cause an imperfect hydraulic seal, with chemical and/or mechanical blocks.
Some wedges are welded on the frame to push the seal fixed on the pad against the frame walls, thus allowing the sealed closing of the passage hole.
