Flomatic Corporation’s Model 80DICL-VFD is a special, patent-pending, submersible pump check valve for use with variable-frequency drive (VFD) control submersible pumps. The valve is designed to minimize flow losses and hydraulic shocks in the pumping system. It features a standard epoxy coating (NSF® approved powder) ductile iron body that incorporates North American Specialty Products patented groove-lock Certa-Lok® type pipe connections to support deep set pumps. An exclusive stainless steel guided poppet system ensures that the valve automatically adjusts noiselessly from high to very low flowrates. Valve seat radius allows 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 and have a high-strength durable design.www.flomatic.com, flomatic@flomatic.com
