Flomatic, a New York-based manufacturer of valves, has introduced a new Model 80S6CL-VFD, patent-pending, submersible pump check valve for use with variable-frequency drive control submersible pumps. These new valves are designed to minimize flow losses and hydraulic shocks in the pumping system.
The new model features a 316 stainless steel body that incorporates a groove lock type pipe connection, called Certa-Lok, to support deep set pumps. A stainless steel guided poppet system aims to ensure that the valve automatically adjusts noiselessly from high to very low flow rates. All internal parts are made from corrosion-resistant materials and have a high strength durable design.
