Kennedy Iron Swing Check Valves UL/FM
Underwriters’/Factory Mutual
Underwriters’ Canada
Kennedy Swing Check Valves are for use where backflow is to be prevented. The disc is designed with ample
tolerances to compensate for seat ring wear. The spinning action of the disc creates a regrinding effect that cleans
the seat ring of foreign particles. The disc is also self-adjusting. All moving parts of these valves are bronze to
bronze, minimizing wear and corrosion problems.
These valves are listed by Underwriters’ Laboratories and approved by Factory Mutual Fire Research Corp. and
have body markings “UL” and “ FM ” signifying the listing and approval.
