The mechanical disconnector protect systems against back pressure, back flow and back syphonage of non-potable water into the public water supply network. It offers better protection than non-return valves as it allows protection up to risk category 4.

Compact, easy-to-maintain design, eliminating the need to remove the separator from the pipeline. The disconnector is characterized by low pressure loss and high flow rate. When the disconnector  is closed, a green color appears under the transparent cover. The disconnector is certified for use in drinking water installations and is KTW approved.

Available in three versions with different opening pressure - A 0,5 bar, B 1 bar, C 1,5 bar.
