<p>The present invention aims at simplifying maintenance, mounting and disassembly operations which are required with valves, and in particular with check valves. Thus, the present invention proposes a solution according to which the closing element (101) of the valve is rotatably fixed to the valve cover (200) so that said cover and said closing element can be simultaneously mounted back by means of a single operation.</p> |
