Althon 100mm Ductile Iron Flap valves are designed and manufactured for use in industrial and domestic effluent and water treatment situations as well as protected river and sea outfalls with gravity flows and are suitable for use with pipework up to and including 100mm diameter.

The manufacture in ductile iron provides strength and rigidity, whilst the flap remains very sensitive to small differential heads of water.

Althon provide their ductile iron flap valves with stainless steel fixing kits, ideal for marine environments. Althon are able to factory fit ductile iron flap valves to their precast headwalls if required.
