Preaction System with DV-5 Deluge Valve
Double Interlock - Electric/Pneumatic Actuation
1-1/2" thru 8" (DN40 and DN200)


Features:
  • Double Interlock - Electric/Pneumatic Actuation
  • The Model DV-5 Double Interlock Preaction System with Electric/Pneumatic Actuation is designed for use in applications, such as refrigerated areas, requiring the maximum degree of protection against inadvertent flooding of the sprinkler system piping.
  • The Model DV-5 Double Interlock Preaction System with Electric/Pneumatic Actuation utilizes a Model DV-5 Deluge Valve and a Riser Check Valve. The Riser Check Valve isolates the Deluge Valve from the system air pressure. The releasing trim for the Deluge Valve utilizes a Solenoid Valve and a Dry Pilot Actuator in a series configuration. The system air pressure holds the Dry Plot Actuator closed, whereas the Solenoid Valve remains closed until it is electrically energized by a Deluge Valve Releasing Panel. The Releasing Panel is operated by either a fire detection device or manual electric pull station.
