A.R.I. NR-47 is a Resilient Disc Check Valve for potable water applications such as pumping stations, surge protection along the pipeline and more. It allows for one-directional flow, preventing the return flow of liquid to its source. The valve features a removable upper cover which enables cleaning and maintenance without removing the valve from the pipeline. The resilient rubber-coated valve disc attaches to a shaft, which is locked into the valve body. Sealing is performed as the disc closes against the valve seat; located at the inlet to the body.
