October 21, 2020 Glens Falls, NY – Flomatic is proud to announce the expansion of their American Iron and Steel (AIS) complaint Model 80DIVFD submersible pump check valve in a new 10” size. Flomatic’s new, special patented submersible pump check valve is now available in an extended size range from 1” thru 10” for use with variable-frequency drive (VFD) control submersible pumps or conventional systems. Standard check valves will “chatter” and be noisy when a VFD goes to low flow, causing premature wear and eventual failure.
The unique Model 80DIVFD valve is designed to minimize flow losses and hydraulic shocks in the submersible pumping system. It features a standard epoxy coated (ANSI/NSF 61 approved powder) ductile iron body to support deep set pumps. An exclusive patented 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. An optional ½” or ¾” size break-off plug, Model “PLG”, is available for easy, safe, and quick-pulling of the pump for servicing. The Model 80DIVFD is more flow efficient than standard check valve models and is rated to 600 PSI and 180◦F (80◦C) max. Also available in an all-stainless steel version, Model 80S6 VFD, in a size range from 1” thru 8”.
