REDI

A range of PVCu non return valves complying with the requirements of BS EN 13564 - ‘Anti-flooding devices for buildings’. Sizes DN100 to DN200 are certified by the German Institute LGA.

These valves are watertight to a pressure of 0.5 bar (5m Head).

These valves have a spigot and socket with integral seal as standard for direct connection to solid walled PVCu pipe but double spigot versions are available to special order for sizes DN400 and above. They can be connected to other pipe material using Mission Rubber Flexible couplings (see separate technical brochure).
