Return flaps
BioAqua non-return valves are designed and installed at stormwater drainage outlets to provide effective protection against backflow. Available in a flange version and pipe mounting version, check valves are made of a durable material, which is PEHD (high density polyethylene).
Non-return valves are widely used in various areas, such as surface water, rainwater or sewage in sewage systems, canals and drainage ditches. The damper is mounted on a flat wall using anchors, it is recommended to use glue-in anchors. To ensure tightness of the connection to the wall, you can use a gasket made of foamed EPDM or a special sealing compound.
Using our non-return flaps has many advantages, including:
Light, but at the same time durable construction.
Corrosion resistance, which guarantees long-term and reliable use.
No need for maintenance and surface protection.
Choice of spigot or flanged connection, tailored to specific requirements.
Wide range of diameters to ensure the valves are perfectly matched to the specific system.
Design flexibility, allowing modifications according to individual requirements.
Possibility of using a counterweight and/or emergency closure.
