4" Industrial PVC Swing Check Valve requires the use of solvent cement on the slip socket ends during installation. Great for commercial and industrial water systems, this valve offers a durable solution to prevent backflow into the system. Backflow can cause many issues including flooding and damage.
For use in irrigation, swimming pool & commercial plumbing applications to prevent backflow. The open position allows for unobstructed continuous flow with minimal head loss.All check valves must be installed with the flow-arrow pointing in the direction of the flow of the system and with the flow arrow on the top side of the valve.
