Kessel PVC check valves
Kessel non-return valves are used within sewerage and drainage systems to eliminate the risk of flood damage by the backflow of sewage or flood water into properties through low level entries.
They connect straight onto a PVC pipe or can be fitted to any other kind of pipe when Flex-Seal couplings are used. Kessel PVC in-line non-return valves can be fitted with a handle to close them off manually, with a second flap to provide dual protection, with an inspection access hatch (Eurofix model), or can be power operated (SWA et FKA models). The Kessel PVC outlet flap valve is ideal for fitting to the end of your pipe network. Kessel Pumpfix check valves have a built-in discharge pump to force the sewage through if the flap becomes blocked.
