Are you searching for sprinklers or alarm check valves?

Mafco offers sprinklers and UL/CUL listed 300PSI alarm check valves that are suitable for wet pipe sprinkler system. Wet pipe sprinkler system is the simplest and most common type of fire sprinkler installation. They are frequently installed in factories, warehouses, office buildings, retail stores, and residences where the potential for freezing does not exist.  This system employs automatic and closed-type sprinklers heads that contain either a heat-responsive glass bulb or a fusible element. The water is contained in the pipes until such time as the heat from the fire activates the heat sensitive element, causing it to release the water through the orifice to the heat source.
