Pump check valve
Flomatic Corporation has introduced a new 1” variable-frequency drive (VFD) special-patented pump check valve designed for use with VFD-controlled submersible pumps. Standard check valves will “chatter” and be noisy when a VFD goes to low-flow conditions, causing premature wear and eventual failure. The Model 100E VFD and 100ES VFD valve are designed to minimize flow losses and hydraulic shocks in the pumping system. In addition, both the inlet and outlet threaded area allow for longer pipe threads.
