NR-47 | Removable Cover Check Valves
PN 6 / 10 / 16
Description
A check valve with a resilient disc, allows for one-directional flow and prevents liquid return to its source.
This valve has a removable upper cover which allows for the cleaning and maintenance of the valve without the need to remove it from the pipeline.
The valve disc is rubber-coated and attaches to a shaft, which is locked into the valve body.
Sealing is performed by the closing of the disc up against the valve seat, located at the inlet to the body.
