Add to CartGroco PNC Series Check Valves are made from PN series cast bronze nipples. A check valve is placed inside to prevent back-flow in plumbing systems. The check valve imposes almost zero flow restriction, and requires less than 1/2 PSI to open. Colored bands indicate flow direction (green to red), confirmed by the permanent laminated tag.
