New line of UL/FM Checks
We have introduced a new line of swing check valves with UL Listing and FM Approval in 2.5” through 12” sizes. These new valves feature 200 psig working pressure, and the standardized lay lengths of AWWA C508-09. They are not directly interchangeable with the older style Mueller® iron bodied UL/FM check valves, which have been discontinued. New numbers will apply to the UL/FM check valves: A-2120-6BB for the bronze disc and seat ring style; A-2122-6B1 for the rubber faced disc with bronze seat ring style.
