To immerse or ballast cages, buoys, containers, etc., we have developed rubber and stainless steel valves. These valves have been designed to be installed on any support without special equipment. They can be attached to the pipes without any alteration to the cage. Valves are used to counterweight the anti-current rings.
These valves are very useful when a pipe is filled with water: the cage can be fixed despite the water inside the pipe. Once it is repaired the water is extracted. The major advantage of these valves is to repair in-situ without having to move the fish out of the damaged cage.
