Flomatic Corporation has introduced a new Model 80S6CL-VFD, submersible pump check valve for use with variable-frequency drive (VFD) control submersible pumps. Standard check valves create noise when a VFD goes to low flow, causing premature wear, and eventual failure. However, pump check valves are designed to minimize flow losses and hydraulic shocks in the pumping system. It features a 316 Stainless Steel body that incorporates North American Specialty Products patented groove lock type pipe connections called Certa-Lok® to support deep set pumps. An exclusive stainless steel guided poppet system ensures that the valve automatically adjusts noiselessly from high to very low flow rates. The radiuses of the valve seat allow a self-cleaning “one point swiping action” by the radius-edged custom molded rubber seal disc. All internal parts are made from corrosion-resistant materials.
