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


Features:
  • Wet Pilot Actuation
  • Opening of a wet pilot sprinkler, 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
