How does a Viking deluge valve work?
How does a Viking deluge valve work?
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 clapper opens to allow water to flow into the system piping.
What is deluge valve?
A deluge valve is a type of system actuation valve that is opened by a detection system that is installed in the same areas as the spray nozzles or by remote manual operation supplying water to all spray nozzles.
How many types of deluge valves are there?
Depending on number of priming chambers two types of deluge valves are found. Single chamber deluge valves are the traditional diaphragm type valves with an inlet chamber connected to the deluge valve supply side and an outlet chamber connected to the fire suppression system side.
How do you activate a deluge valve?
How is a Deluge System activated? The sprinkler heads on a Deluge system are fused together and operate as one when activated. The valve is opened when activated by heat or smoke detection systems. Once activated, the water is released into the piping and out of the sprinkler heads.
How do you use a deluge valve manually?
Under FIRE conditions, water pressure is released from the control chamber, by opening the local manual release or, when fitted, by opening the hydraulic remote Manual Release [7]. This opens the deluge valve allowing water to flow into the system piping and to the fire extinguishing devices.
Where are deluge valves used?
What are Deluge Valves? Deluge systems deliver large quantities of water, over a large area, in a relatively short period of time. They are commonly used in fixed fire protection systems whose pipe system is empty until the deluge valve distributes pressurised water from open nozzles or sprinklers.
How do you reset a Viking dry valve?
To reset the valve, simply re-establish air pressure to the system and pressurize the valve’s unique priming chamber. In a fire condition, air pressure is lost and the priming chamber compresses allowing water to pass through the valve and into the sprinkler system piping.
What is deluge testing?
Deluge testing is a costly business. Wet testing causes corrosion and/or salt crusting and growth of organisms in flow pipes and nozzles. Spray of sea water over the entire production facility is a hazard for the expensive processing equipment. The excess of waste water will flood the sump tanks.

What is the difference between deluge and sprinkler system?
The main difference between a deluge sprinkler system and any other sprinkler system is the sprinklers themselves. The sprinkler heads in wet pipe systems, dry pipe system, and even pre-action systems all remain closed unless they detect heat from a fire. A deluge system, however, has open sprinkler heads at all times.
