Check Valves operate with VFD-controlled submersible pumps.

Press Release Summary:

Designed to minimize flow losses and hydraulic shocks in pumping systems, Models 80E VFD and 100E VFD can be installed in horizontal or vertical piping. Units have unleaded alloy body available with 1, 2, 3, and 4 in. threaded female NPT connections. With guided poppet system, valves automatically adjust noiselessly from high to very low flow rates. Radiuses of valve seat allow self-cleaning, one point swiping action by radius-edged custom molded rubber seal disc.

Original Press Release:

Flomatic Corporation Introduces a New, Special Patent Pending Pump Check Valve Especially Designed for Use with Variable-frequency Drive (VFD) Controlled Submersible Pumps

High Quality Valves Built to Last. . .

Glens Falls, NY – Flomatic Corporation introduces a new, special patent pending pump check valve especially designed for use with variable-frequency drive (VFD) controlled submersible pumps. Standard check valves will “chatter” and be noisy when a VFD goes to low flow conditions, causing noise, premature wear, and eventual failure. The unique Model 80E VFD and 100E VFD valve is designed to minimize flow losses and hydraulic shocks in the pumping system. It features an unleaded alloy body available in sizes 1”, 2”, 3” and 4” threaded Female NPT connection. An exclusive guided poppet system (stainless steel in 2” thru 4”), 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 durable high strength design. The valve can be uniquely installed in either horizontal or vertical piping installations.
