Althon HDPE 900mm Flap Valve

Althon 900mm HDPE flap valves can be used in surface, sewer and water process applications. Our 900mm HDPE flap valves are a simple and highly effective way to prevent water backflow into a system. 900mm HDPE non return flap valves are manufactured in HDPE and stainless steel grade 316L. Althon HDPE flap valves are lightweight and high strength. Our HDPE flap valves are therefore easy to install and require very little maintenance.

Our 900mm HDPE flap valves are manufactured with a square backplate. This arrangement makes them easy to factory fit to our range of precast concrete headwalls. They can also be retro fitted to in-situ concrete headwall and other outfall structures or manholes. When sending out HDPE flap valves to retro fit to an existing structure we will supply an EPDM seal, chemical anchors and stainless steel fixings. Althon HDPE flap valves have a design life of 50 years. Our 900mm HDPE flap valves are suitable for use with pipework up to 900mm.
