Deluge & Preaction Systems

Viking's new lighter and smaller VXD valves offer one platform for multiple system types, and are available in multiple sizes of groove by groove and flange by flange models. Additionally, the VXD deluge valve is offered in electric, pneumatic and hydraulic release, while the preaction VXD valve is offered in electric and electric/pneumatic release. The VXD line is available pre-trimmed or with loose trim.

To order a Model E or Model F deluge or preaction system, first select the desired deluge valve and the appropriate deluge valve trim.  Next, choose a releasing trim and releasing device(s) depending on your application.  For preaction systems, a riser check valve must also be ordered, as well as a VFR-400 release control panel (for systems that are released electrically).

To simplify the process, Viking also offers several factory assembled options.  The Model G preaction systems are shipped completely preassembled including the deluge valve, trim, releasing devices/trim, switches, gauges, and a water supply control valve (release control panel ordered separately). 

Additionally, Viking offers all deluge and preaction system in a TrimPac configuration, which includes conventional trim, releasing trim, and releasing devices assembled in a steel enclosure which can be mounted to the riser or to a wall.  Flexible hoses are provided to connect TrimPac to the deluge valve.  The deluge valve and a drain package must be ordered separately, as well as the VFR-400 release control panel for preaction systems.
