1 DESCRIPTION
The Viking Model VXD Deluge Valve is a flood valve with one moving mechanism.
The Deluge Valve is used to control water flow in Deluge and Preaction sprinkler
systems. The valve is held closed by system water pressure trapped in the priming
chamber, keeping the outlet chamber and system piping dry. In fire conditions, when
the releasing system operates, pressure is released from the priming chamber. The
Deluge Valve diaphragm opens to allow water to flow into the system piping.
Features
1. Field replaceable diaphragm
2. Designed for installation in horizontal or vertical position
3. Automatically resets without opening the valve
4. Compatible with Hydraulic, Pneumatic and Electric Release Systems
