Flomatic Corporation is bringing a new 1-inch sized variable-frequency drive (VFD) special patented pump check valve to groundwater professionals. The Model 100E VFD and 100ES VFD are designed for use with VFD-controlled submersible pumps.
Standard check valves tend to “chatter” and make a lot of noise when a VFD goes to low flow conditions, causing annoyance, premature wear and eventual failure. The new valves are designed to minimize flow losses and hydraulic shocks in the pumping system.
Both the inlet and outlet threaded area allow for longer pipe threads. An exclusive guided poppet system (optional SS poppet), ensures that the valve automatically adjusts noiselessly from high to very low flow rates. The unleaded bronze valve body incorporates internal parts that are made from corrosion-resistant materials and have a durable high-strength design.
The valves can be uniquely installed in either horizontal or vertical piping installations. Physical valve dimension and pressure rating are the same as for Flomatic’s Model 100LE.
