What is the purpose of a deluge valve?
Deluge systems are designed to protect high-hazard areas such as tunnels, oil refineries, chemical facilities, offshore platforms, and power plants. These locations frequently contain highly flammable, combustible, or explosive materials that require robust fire protection systems.
How many types of deluge valves are there?
Deluge valve is available with several trims including wet pilot, dry pilot, electric release, manual release, etc.
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 I choose a deluge valve size?
When choosing a deluge valve, check the specs to be sure the valve has a high Kv (flow coefficient) for high flow capacity, suitable for the size and application. In the event of a fire, multiple valves in the system need to be opened, which can decrease the pressure enough to interfere with proper valve performance.
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.
How do you use a deluge valve manually?
The 400Y-1D is activated manually by opening the local Manual Release Valve attached to the valve’s control trim. The 400Y-1D is ideal for use as a locally operated deluge valve for water spray or foam system nozzles.
What type of valve is a 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 does deluge system work?
A deluge fire protection system has unpressurized dry piping and open sprinkler heads. The system is directly connected to a water supply and when the system is activated, a deluge valve will release the water to all the open sprinkler heads. The valve is opened when activated by a heat or smoke detection system.
Where are deluge valves used?
Deluge systems are used in high hazard areas such as power plants, aircraft hangars, and chemical plants. These systems are very effective in hazardous areas because they release water or another fire suppressant to all the open sprinkler heads simultaneously.

What are the four types of sprinkler systems?
Types of sprinkler systems permissible by NFPA 13, Standard for the Installation of Sprinkler Systems, are wet, dry, preaction, and deluge.
What are three operations of the deluge system?
The main purposes behind using deluge systems are any one or combination of the following :
- Extinguishment of fire.
- Control of burning.
- Exposure protection.
- Prevention of fire.
What is the difference between sprinkler system and deluge system?
In a traditional sprinkler system, the pipes are filled with water and the sprinkler heads are closed. A deluge system is a dry system which means it is not at risk for having frozen pipes. The pipes of traditional sprinklers can freeze when exposed to cold temperatures because they are filled with water.
What are the 3 types of sprinkler systems?
3 Types of Fire Sprinkler Systems
- Wet Fire Sprinkler System. A wet fire sprinkler system is one of the most common options on the market.
- Dry Fire Sprinkler System. A dry fire sprinkler system is filled with pressurized air, rather than water.
- Preaction Fire Sprinkler System.
What are 4 types of sprinkler systems?
How does water deluge work?
What is NFPA standard for sprinkler systems?
NFPA 13 is an installation standard and does not specify which buildings or structures require a sprinkler system. NFPA 13 specifies how to properly design and install a sprinkler system using the proper components and materials after it has been determined that a sprinkler system is required.
What is the standard pressure for fire sprinkler?
NFPA 13 establishes a minimum pressure of 7 psi, even when the calculation procedure yields a smaller value. This ensures that sprinklers produce the correct spray pattern.
What is the k-factor in fire sprinklers?
K-factor helps to calculate the discharge rate from fire sprinkler heads. It’s calculated in imperial units for the United States by using the flow in gallons per minute (gpm) and the pressure in PSI. Metric calculations use the flow in liters per minute and pressure in bar.
How do I calculate sprinkler pressure?
Finding the Flow Rate or GPM
- Equation: Static pressure – friction loss +/– change in elevation = psi available to sprinkler.
- Example: You measure your static pressure at 65 psi and your total flow rate from your spigot at 10 gpm.
How do I calculate GPM?
The formula to find GPM is 60 divided by the seconds it takes to fill a one-gallon container (60 / seconds = GPM). Example: The one-gallon container fills in 5 seconds, breakdown: 60 divided by 5 equals 12 gallons per minute.
What is the minimum pressure required at sprinkler head?
What is K-factor in sprinkler system?
What is gpm per pipe size?
Water Flow (GPM/GPH) based on Pipe Size and Inside/Outside Diameters
Assume Average Pressure (20-100PSI). About 12 f/s flow velocity | ||
---|---|---|
3″ | 2.9 – 3.05″ | 273 |
4″ | 3.85 – 3.95″ | 480 |
5″ | 4.95″ – 5.05″ | 750 |
6″ | 5.85 – 5.95″ | 1100 |
What GPM means?
Gallons Per Minute
GPM means Gallons Per Minute. Also known as “flow rate”, GPM is a measure of how many gallons of water flow out of your shower head each minute.
