Heavy-duty Dry Alarm Valve
The Dry Alarm Valve is the heart of a dry-pipe sprinkler system. It keeps pressurized air in the pipes instead of water, preventing freeze-ups in cold areas. When a sprinkler opens, the air escapes, the valve trips in seconds, and water rushes to the heads to extinguish the fire. Built for harsh climates, it offers reliable, freeze-proof protection year-round.
