Check valves of the Metal Work Line-on-Line series
The VNR L check valve belongs to the LINE ON LINE® family, which means it can be connected to all the other components in series or in parallel.
Available in the version for pipe-pipe connection with two push-in fittings, and in the version for thread-pipe connection with a brass nickel-plated male thread and a push-in fitting. It is still the only check valve with holes for wall mounting
