Manufacturer Information:

For over 50 years, Flomatic’s Ductile Iron Check Valves have been an industry-proven favorite. The Ductile Iron series (DI) is an industry proven heavy duty in-line poppet style valve designed to prevent flow reversal. When pumping from a well, water is allowed to flow through the valve and then closes automatically when the pump is shut off to prevent backflow. Flomatic’s DI series are among the most popular valves in the water well industry today. These valves are specifically designed for use with submersible pumps or other applications where it is necessary for the check valve to be installed in a well casing.

Operation: Flomatic Model 80DI series ductile iron check valves are designed to provide years of trouble free operation without maintenance when properly sized and installed in an appropriately selected pumping application, in regards to flow and maximum system pressures.

Construction: The Flomatic check valve body is constructed to handle the rated system flow and pressures as stated, and to support the combined weight of the submersible pump, pipe, and the water in the riser pipe. In addition, the valves are uniquely designed to mitigate some of the hydraulic water shocks associated with well water pumping when the following check valve installation instructions are adhered to.
