DV-5 Deluge Valve,
Diaphragm Style, 1-1/2" thru 8" (DN40 thru DN200),
Deluge System - Dry Pilot Actuation


Features:
  • Dry Pilot Actuation
  • Opening of a dry pilot sprinkler, releases pneumatic pressure from the pilot line. In turn, the Dry Pilot Actuator opens and releases water from the Diaphragm Chamber faster than it can be replenished through the 1/8 inch (3,2 mm) restriction provided by the Model ASV-1 Automatic Shut-Off Valve in the diaphragm supply connections.
  • This results in a rapid pressure drop in the Diaphragm Chamber and the force differential applied through the Diaphragm that holds it in the set position is reduced below the valve trip point. The water supply pressure then forces the Diaphragm open permitting water to flow into the system piping, as well as through the Alarm Port to actuate the system alarms.
  • Listings and Approvals: UL, C-UL, and FM
