Model VXD Deluge System with Hydraulic Release

Hydraulically controlled deluge systems require a hydraulic release system equipped with thermostatic (rate-of-rise) releases, and/or fixed-temperature releases, and/or pilot sprinkler heads. In fire conditions, operation of a releasing device on the hydraulic release system opens the deluge valve, allowing water to enter the system piping. Water will flow from any open sprinklers and/or spray nozzles on the system.
