1. DESCrIPTIoN
The Viking Model F-1 Deluge Valve is a quick opening, differential diaphragm and 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 pres-
sure 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 clapper opens to allow water to flow into the
system piping.
Features:
1. Field replaceable Diaphragm and Seat Rubbers
2. Designed for installation in the horizontal or vertical position
3. Designed to be reset without opening the valve
4. Compatible with Hydraulic, Pneumatic and/or Electric Release Systems
