The Watts 911-M3 is a combination of the 9D back flow preventer and the 1156F feed water pressure regulator that is intended for use on systems like hydronic heating, sprinklers and boiler feed lines to provide water through the system and prevent backflow when supply pressure falls below system pressure; efficiently delivering quick system filling and purging. This fill valve and backflow preventor from the 911 series is pre-assembled which helps you save time and eases the process during installation.
The 911-M3 is made from brass and bronze materials -- it only ensures you durability and product longevity while having the full capacity to consistantly work even in extreme temperatures. It has 1/2" union solder inlet and NPT threaded outlet connections. The maximum pressure of this fill valve and backflow preventor is 100 psi (6.9 bar).
