STAUFIX - Клапан обратной воды с двойным флапом
Backwater valve Staufix DN 200, exposed, Type 2 R.
The backwater valve for wastewater with and without sewage (ÖNORM Austria) is equipped with two mechanical flaps that close automatically in the event of backwater. One flap also serves as a manually lockable emergency closure. Thanks to the modular KESSEL system, existing systems can be easily converted to the StaufixControl backwater valve.
