FLAP VALVES HDPE
Flap Valves HDPE material water control devise (ICD), water management and flow control.
Storm Event back flow protection up to 32 ft. of flood water head
Flap valves are designed for use in water control systems and flood protection. They prevent back flow from the intrusion of tidal waters, storm waters back through the discharge structure. HDPE Flap valve may be installed on all size openings. Easy to install - No grouting required - Light weight - Virtually maintenance free.
Available mounting designs include
Flap Valves Flange mounted : flap valve for attachment to a flanged at the end of a pipe.
Flap Valves Tidal Water: flap door is mounted at a 10 degree angle for positive closure.
Flap Valves Permanent Underwater : the valve is always water covered, 10 degree.
Flap Valves Pressure Line : Flap Valves for pump flow outfalls with venting.
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 out falls. Outfalls that are not equipped with back flow protection can have a devastating effect in the event of heavy rainfalls, storms and higher than normal tides.
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.
HDPE (High Density Polyethylene) Flap Valves, are lightweight, corrosion resistant non-return check valves for the prevention of flood damage.
