FLAP VALVES HDPE
HDPE Flap Valves and Inlet control devise (ICD), for water management and flow control. Major storm backflow prevention up to 32 ft. of flood water

Flap valves are designed for use at the discharge point of water control systems. They prevent back flow or intrusion of tidal waters or storm waters back through the discharge structure. HDPE Flap valve may be installed on all size discharge openings.
Easy to install - No grouting required - Light weight -Virtually maintenance free.
Select from Menu on the Left. Available mounting designs include:
- Wall mounted – this basic flap valve can be easily mounted to a flat wall to prevent reverse flow.
- Pipe mounted – this type of valve can be mounted at the pipe end.
- Flange mounted Valves – are designed for attachment to a flanged pipe (Flange mounted to PN10 )
- Tidal Flap Valves – on angle for tidal situations, they have the flap door mounted at a 10 degree angle.
- Different shaped outfalls - Square, Rectangular, Round, Elliptical.
- Pressure Line Flap Valves - Flap Valves for pump flow outfalls.
Typical applications include discharges to tidal waters, manholes, culverts, reservoirs, ponds basins and standpipes. Flap Valves permit the outflow of water while preventing back flow.
Flap Valves can be as simple as a small 100 mm HDPE flap or much larger Flap Valve for ocean outfalls. Outfalls that are not checked can have a devastating effect on structures and low elevation behind it.
HDPE flap valves require very low opening pressure to operate (only 5mm water level difference). When water on the face side of the flap valve rises above water on the back side, it closes automatically to prevent back flow.
Flap Valves may be installed above the waterline or below the water table.
HDPE (High Density Polyethylene) Flap Valves, are lightweight, corrosion resistant Non-Return check valves for the prevention of reverse flows.
