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.
