Sure Flow Flanged Elastic Swing Check Valves are suitable for municipal and industrial applications. They have a ductile iron body with ASME Class125# flanges. The internal body is epoxy coated. The one-piece molded disc has a steel reinforced insert to ensure closure.
While in the open position, this check valve will allow 100% uninterrupted flow. The one-piece disc hinge and disc can be repaired without removal of the valve from the line.
Optional: A Backflow Rod can be installed and used for draining or pump priming. This option is a safe and effective way to manually activate the valve.
