10" inch VXD Deluge system with Pneumatic Release, Galvanized, Loose Trim
Viking VXD Deluge Systems utilize a Viking Model VXD Deluge Valve to control the water supply to system piping equipped with open sprinklers and/or spra nozzles. The system piping remains empty until the deluge valve is activated by operation of the release system. Deluge systems are commonly used where it is desirable to simultaneously spray water from all open sprinklers and/or nozzles on the system when it operates.
Pneumatically controlled deluge systems require a pneumatic release system, equipped with thermostatic (rate-of-rise) releases and/or fixed-temperature releases, and/or pilot sprinkler heads. Release trim for the pneumatically controlled deluge valve includes a pneumatic actuator normally held closed by the air pressure maintained in the pneumatic release system. In fire conditions, operation of the pneumatic release system causes the deluge valve to open and allows water to enter the system piping. Water will flow from any open sprinklers and/or spray nozzles on the system.
*Loose trim packages come loose in a box and assembly is required. These packages do NOT include the deluge valve.
