Check valves a special type of isolation valve
areas of application
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:
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.
