The device (1) has two fluid circulation paths (3a) for circulating fluid. A movable valve (7) is arranged between the two paths, and is provided with flap gates, where one of the flap gates belongs to movable hollow bodies (11, 18) traversed by a leakage chamber. The flap gates avoid fluid circulation between the two paths in a closed position of the valve to authorize connection between the two paths in an open position of the valve. Another flap gate (9c) is connected with the two flap gates in a sealed manner at corresponding cleaning situations. The latter flap gate is made of Polyether ether ketone (PEEK). |
