The compact size of the NR-010 makes it easily installable between two flanges and is supplied with its own flange seals. The disc spring assembly is built outside of the flow cross-section and can be effortlessly replaced without removing the check valve from the line. It is designed for free flow of liquids without interference and with minimal head loss.
The NR-010 has a working pressure of 10 bar and is available in sizes from 1½â€ to 10”. A comparable line of A.R.I. check valves, the NR-020, is available with a working pressure of 16 bar.
