Ostendorf Non-return valves

Ostendorf non-return valve is a stop valve that is installed in systems of internal and external sewerage. It is used to block the backflow of sewage - when a backflow occurs, the shut-off valve automatically closes the sewer system. Also check valves prevent the entry of rodents and insects into the room.
