0224s Frame Flap Valve UFT-FluidFrame
Intended Purpose
If the water level in the downstream waters rises during flooding, low weirs run the risk of flooding by backwater. River water then backs up in the sewer system and overloads the sewage treatment plant. It may even flood cellars and streets.
Overflow weirs often have a considerable length. Such large openings can be reliably sealed with rigid flaps such as the Frame Flap Valve UFT-FluidFrame. During floods, it prevents massive backflow from the waterbody into the sewer system or into the storm tank.
Properties of the Frame Falp Valve UFT-FluidFrame
- the frame flap valve opens at low opening pressure in flow direction
- compact structure
- the sealing lip presses firmly against the frame and provides a circular seal
- no external energy required
- robust, low-maintenance mechanism
- retrofitting by doweling possible
- high pressure head permissible
