Dry Alarm Valves


  • Info
  • cULus & FM approved
  • The Globe Model F-3 and G-3 Dry Pipe Valves are a vital control unit in dry pipe automatic sprinkler systems supervisory air under pressure is used to prevent freezing that would certainly occur with ordinary wet pipe systems
  • Serves as a connecting link between the source of water supply and the automatic sprinklers, and must react promptly when it receives a signal from the protected area that a fire condition has developed and water is therefore quickly needed
  • This signal is generated by the opening of one or more sprinklers which causes a quick drop in system supervisory air pressure resulting in a loss of the differential ratio
  • The single clapper assembly design in the Globe Model F-3 and G-3 dry pipe valves, provides several areas exposed to working pressures which, in combination, create a differential force ration between system air pressure and water supply pressure
  • A single-latching lever is provided as a means of holding the clapper in
  • Once the valve has operated, a special latch holds the clapper open until manually reset by experienced personnel
  • The body of the Dry Pipe Valve is constructed of high tensile strength cast iron having considerable ductility to reduce damage in field handling
  • All interior operating parts are machined from highly corrosive resistant copper alloys, each having high strength and good wear resistance
  • Rubber parts are of selective materials which have good abrasive resistance and long life expectancy in terms of resiliency
  • The single clapper assembly design in the Globe Model D dry pipe valve, provides a differential force ratio of approximately 6:1 between system air pressure and water supply pressure
