Flomatic has announced that all of its VFD Series Check Valves are NSF/ANSI 61 certified for drinking water systems.

In addition to NSF/ANSI 372, the low‐lead standard has a weighted average of 0.25 per cent lead content by dry weight. NSF/ANSI 61 Drinking Water Standards are a set of national standards which establish stringent requirements for equipment that comes in contact with potable water, the company said in a press release. The test uses different water pH levels to a more challenging chemical certification.

Flomatic  has a wide range of patented VFD check valves configurations in unleaded bronze, stainless steel and ductile iron, specially designed for use with variable frequency drive (VFD) controlled submersible pumps. A standard check valve will “chatter” and be noisy when a VFD goes to low flow conditions, causing noise, premature wear and eventual failure.
