STAUFIX - Одноплоский обратный клапан
The backwater valve for wastewater without sewage is equipped with one mechanical flap which closes automatically in the event of backwater and also serves as an emergency closure to be closed by hand. Thanks to the modular KESSEL system, existing systems can easily be supplemented by a second backwater flap.
