Flomatic Corporation introduces a new Model 80DICL-VFD, special patent-pending submersible pump check valve for use with variable-frequency drive (VFD) control submersible pumps. Standard check valves will “chatter” and be noisy when a VFD goes to low flow, causing premature wear and eventual failure.

These unique valves are designed to minimize flow losses and hydraulic shocks in the pumping system. The Model 80DICL-VFD features a standard epoxy coating (NSF-approved powder) ductile iron body that incorporates North American Specialty Products’ patented Certa-Lok groove-lock-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 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 and have a high-strength durable design.
