Manufacturer Information:

Operation: Flomatic Model 80DI-VFD 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.

The American Made and one of the first-ever Variable Flow Demands (VFD) Check Valve for the Submersible Pump Industry continues to lead the way as the industry's pioneer. The patented 80DIVFD is uniquely engineered to allow the valve to operate in a wide flow range which typically is the case with VFD controlled pumps. The exclusive poppet system ensures that the valve automatically closes tight and noiseless after each pump cycle. A self-cleaning seat/stem helps increase service life and the optional Break-Off plug improves convenience when servicing the system.

Available in Bronze, Stainless Steel, and Ductile Iron 1" thru 10", Flomatic's 80DIVFD Series is a clear and reliable choice, another High Quality Valve Built to Last.
