Althon HDPE flap valves for pipework from 600mm up to 1500mm can be used in surface, sewer and water process applications. HDPE flap valves are a simple and highly effective way to prevent water backflow into a system. Our HDPE 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, responsive and very reliable. Althon HDPE flap valves start at 100mm in diameter up to 1500mm as standard.
Our 600 – 1500mm range of 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.
We would be pleased to assist with bespoke flap valves as and when required. Please visit the Bespoke HDPE Flap Valve section of our website. Althon HDPE flap valves have a design life of 50 years.
