Alwa-Kombi-4 with fitted Sanpress fittings
Accessories
The Alwa-KFR is used as shut-off valve with backflow preventer in potable water installations. The
downstream installation is isolated by shutting off the valve with the handwheel. The integral backflow
preventer with an opening pressure of <=10 mbar stops water from flowing back through the valve.
The valve insert with integrated backflow preventer is available as spare part and fits into all valve
housings with dimensions according to DVGW so that normal shut-off valves can be upgrated to shut-
off valves with backflow preventer. Alwa-KFR valves are available with various pipe connections. Alwa-
K-KFR valves are equipped with larger external threads specially suitable for pipe connections of
various plastic pipes. Valves with draining facility allow draining of the system over the valve.
For potable water systems.
