Flomatic 10'' AIS compliant check valve

摘要

Flomatic announces the expansion of their American Iron and Steel (AIS) compliant Model 80DIVFD submersible pump check valve in a new 10'' size. Flomatic's new, special patented submersible pump check valve is now available in an extended size range from 1'' thru 10'' for use with variable-frequency drive (VFD) control submersible pumps or conventional systems. Standard check valves will "chatter" and be noisy when a VFD goes to low flow, causing premature wear and eventual failure.
