Althon GRC Large Headwall + 300mm Spigot Mounted Flap Valve
The Althon GRC range of headwalls with non return valves provide a cost effective option to reduce erosion at the point of discharge whilst preventing backflow up the pipeline during a storm event.
Our GRC headwalls have knockout webs to suit different pipe diameter and the non return valves supplied with the headwall push fit to suit the ID of the connecting pipework and are supplied with a suitable seal to secure the valve into the pipe
We can offer coloured headwalls in 4 colours but the final shade is affected by many influences.
