Storm gate PP DN 160 single flap type 1, for external sewage systems ZB160

Flood and Rodent Protection in One

The KARMAT storm valve is a reliable solution for protecting rooms from the effects of floods, heavy rainfall, and sewage reflux. Mounted on drain pipes, it effectively protects against flooding of basements, boiler rooms and other low-lying areas. Not only water poses a threat – this valve also acts as a barrier against rodents, preventing them from entering the building through the sewer system.

Design and Operation

The Type 1 storm valve, with a nominal diameter of DN 150 and an outer pipe diameter of 160 mm, is made of durable polypropylene (PP-R). This material is characterized by high resistance to corrosion, mechanical damage and the action of aggressive chemical substances contained in sewage. A key element is the chrome-nickel flap cover, which not only protects it from damage but also protects the seal from rodents and its displacement during flow. This ensures long-lasting and trouble-free protection. The design of the device allows maintaining the full throughput of the sewage system.
