2- System with Hydraulic Release
1. Description
The T
OTALPAC2 System with the Viking Deluge Trim utilizes
a Viking Deluge valve (A1) to control water flow into system
piping equipped with open sprinklers and/or spray nozzles.
The system piping remains empty until the Deluge Valve is
activated by operation of the release system.
Hydraulically controlled deluge systems require a hydraulic
release system, equipped with thermostatic (rate-of-rise)
releases, and/or fixed temperature releases and/or pilot
heads.
Deluge systems are designed so the Deluge valve will
open when a detector on the hydraulic release system
operates. When the Deluge Valve opens, water will flow
into the sprinkler piping and out of any open sprinklers,
open spray nozzles and any opening on the system.
Deluge TOTALPAC2 Systems are commonly used where it is
desirable to simultaneously spray water from all open
sprinklers and/or spray nozzles on the system when the
system operates.
