Non-return valves

The task of non-return valves or backflow valves is to prevent the flow of the media in a certain flowing direction. Our product range also covers non-return valves for cryogenic applications.

The FEMA non-return valves in our range are either piston or swing non-return valves. Disc-type non-return valves installed between flanges belong to GESTRA’s RK Disco series. Non-return valves are available with flanges, with weld ends or for installation between flanges.

Depending on the nominal size, pressure rating and, above all, pressure loss, a non-return valve suitable for a certain process can be selected from our product range. It is also important that non-return valves are dimensioned and not selected based only on the pipe size.
