Storm valve PP dn 200mm for concrete wells type 0, with removable flap, universal, for external sewage systems, with 140cm extension UZBBW200

Flood and sewage backflow protection

The KARMAT storm gate is a reliable safeguard for your sewage system. It prevents uncontrolled flow of rainwater or sanitary sewage into the building, protecting basements and utility rooms from flooding. This is particularly important during heavy rainfall, thaw or floods, when the risk of water backflow is greatest. The gate can be used in both new and existing installations – installation is possible in concrete wells from various manufacturers.

Design and functionality

The UZBBW200 storm gate has been designed with ease of use and maintenance in mind. It is equipped with a removable check flap, which can be easily removed to the surface using the included rod with a length of 140 cm (consisting of two 70 cm extensions each). This functionality eliminates the need to enter the well during cleaning or inspection. Thanks to a special strip seal, patented by Karmat, the valve provides a tight seal regardless of the pipe wall thickness. The chrome-nickel coating of the flap, seals and lever effectively protects against corrosion and prevents rodent access.

Advantages for the installer and end user

• Versatility: Fits most concrete wells available on the market, simplifying the selection of the appropriate model.
• Easy installation: Does not require complicated modifications to the existing installation – it can be mounted directly on the outlet of the sewer pipe.
• Convenient maintenance: The removable flap allows quick access to the valve mechanism without having to enter the well. This saves time and minimizes the risks associated with working in confined spaces.
• Effective protection: Protects against flooding caused by sewage and rainwater backflow, which translates into property safety and building comfort.
• Durability: Made of high-quality materials resistant to corrosion and chemical substances, which guarantees a long service life.
• Rodent protection: The chrome-nickel coating of the flap and appropriate sealing prevent rodents from accessing the sewage system.
• Possibility of use in rainwater drains: Possibility of mounting on a concreted outlet of a rainwater drainage pipe leading to rivers or water reservoirs.

Thanks to these features, the KARMAT storm gate is an investment that provides peace of mind for both the installer and the end user.
