Standard check valves will “chatter” and be
noisy when a VFD goes to low flow, causing premature wear and eventual failure,
said Flomatic in a news release. These valves, which are designed for use with
variable-frequency drive (VFD) control submersible pumps, are designed to
minimize flow losses and hydraulic shocks in the pumping system.


They feature a standard epoxy coating (NSF-approved
powder) on a ductile iron body that incorporates patented called Certa-Lok groove
lock type pipe connections to support deep-set pumps. A stainless steel guided
poppet system ensures the valves automatically adjust 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 moulded
rubber seal disc. All internal parts are made from corrosion-resistant
materials and have a high-strength, durable design.
