Check valves

Flomatic Corporation introduces 1- and 1.25-inch Model 80DI VFD, special patented, submersible pump check valves for use with variable-frequency drive (VFD) control submersible pumps. These are designed to minimize flow losses and hydraulic shocks in the pumping system. The valves feature a standard epoxy coating (NSF-approved powder) ductile iron body to support deep set pumps. An exclusive, stainless steel, guided poppet system ensures the valve automatically adjusts noiselessly from high to very low flowrates. 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. http://www.flomatic.com,
