ECO-FLAP® Flap valves
Designed for use in surface water and gravity drainage systems, the ECO-FLAP® flap valves are usually installed on river, estuary and sea outfalls to prevent backflow into the sewer and the possible flooding of property. The ECO-FLAP® range is available in two models.
- ECO-FLAP® Flange fixing onto a concrete wall or on an ISO PN 10 pipe flange,
- ECO-FLAP® N End-Line Valve for fixing onto all types of pipeline, either directly or with a NORHAM Flexible coupling.
