The check valve is a special type of isolation valve. Check valves are used to prevent the inversion of the flow direction of the medium in the technological pipeline. We offer a wide range of check valve designs: folding valves, butterfly folding valves, check valves with inclined seat, two-piece check valves. You can choose between flange construction or intermediate flange construction. When installing check valves with large pipe diameters, there is a risk of a closing pressure surge from the check valve. Hydraulic dampers are installed in order to avoid this closing of the check valve and thus the closing pressure shock. As a special version, it is possible to install a protective cover for the handle. It protects the operating personnel when blowing off the non-return valve.
