NR-040 | Check Valve with Removable Cover

The NR-040D series Swing-type Check Valve allows for one directional flow and prevents the return flow of the liquid to its source. The check valve is designed with a removable top cover which allows for cleaning and maintenance of the check valve without the need to remove it from the pipeline. The disc is attached to the check valve body with the aid of an arm. The check valve seals with the closure of the disc against the sealing ring which is located at the opening of the check valve body.
