Preassembled. Proven. Reliable. The PrePaK™ Cabinet in the Field


From Sports Arenas to Data Centers—PrePaK™ in Action

At the University of Notre Dame, a Reliable PrePaK™ cabinet was installed to protect one of the campus’s critical telecommunications areas. Its compact, preassembled design makes it easy to install and doesn’t disrupt daily activity. Built and tested in Liberty, South Carolina, the PrePaK combines the trusted DDX valve now with optional Vapor Pipe Shield® for added corrosion protection. The same advantages make it ideal for data centers, libraries, museums, and other occupied environments where downtime isn’t an option and reliability matters most. The PrePaK proves that powerful fire protection can be simple, safe, and installation-ready. If you want to see more about Campus Fire Protection, see our video.

The Heart of the System: The DDX Valve

Model DDX
Crafted from stainless steel, the clapper, seat, and push rod assembly protects against corrosion.
Resetting the clapper of the Model DDX Valve is easily accomplished using the external reset knob at the rear of the valve.
Time- and field-proven mechanical deluge valve with latching clapper. Helps prevent false-tripping and utilizes a single main drain valve. Valve sizes from 2” (50 mm) to 8” (200 mm).
