The latest product from MTA is the intelligent check valve MwStop®. This can be installed in practically any pipe,  in just a few minutes and provides immediate effective protection against flooding, foreign bodies and annoying odours.

The wide MwStop® range ensures that the right MwStop® model is available for every application, be it for backwater protection of the sewer system, for use in rainwater pipes or for preventing odour formation in mixed sewers.

Unlike all other backwater valves available today, MwStop® can be installed in any position from horizontal to vertical, in inlet and outlet pipes, pumping stations, shafts and chambers.

The installation is simple and can be carried out without any structural measures. MwStop® can be adjusted to provide a solution for virtually any pipe diameter using gaskets of various thicknesses.
