Dry System Valves

Reliable dry system valves are designed to protect areas subject to temperatures below 40°F (4°C). Dry sprinkler systems have compressed nitrogen or air in the system piping, with water under pressure held below the clapper of the valve. When a fire occurs, and the sprinkler activates, nitrogen or air pressure is relieved from the system piping, causing the valve to open and water to flow into the system pipe and any opened sprinklers.

Reliable offers both low and standard pressure dry valves in a variety of sizes, inlet and outlet connections, and pressure ratings. Low-pressure dry systems featuring the Reliable DDX-LP can improve water transit times following the operation of the valve, and in some cases, eliminating the need for a quick opening device.

Reliable supplies a variety of dry pipe valves involved in fire sprinkler systems.

How Exactly Do They Work?

Fire sprinklers are a part of a vital system that help protect your building against fire. They are a part of a complicated system and they can become even more complicated because there are numerous different types of systems. Fire sprinkler systems include:

For this week’s blog post we will be focusing on Dry Pipe Fire Sprinkler Systems. Dry Pipe Systems are the second most common fire sprinkler system next to Wet Pipe Fire Sprinkler Systems. They are named after the fact that the fire sprinkler pipe has no water in it, so it is always dry.

How Do They Work

Dry Pipe Fire Sprinkler Systems are a bit more complicated than a Wet Pipe System. A Dry Pipe System consist of pipes that contain pressurized air instead of water. Then there is a check valve that holds the water supply back from the pipes. A fire sprinkler head is then triggered when it is heated to temperature. This vents the air from the fire sprinkler head through the fire sprinkler pipe. The air pressure within the pipes then drops which opens the check valve and allows water to flow through the pipe to the vented fire sprinkler head. Because each sprinkler head operates individually, water will only flow out of a sprinkler head if it has been heated to the temperature that allows it to vent.

Pros and Cons

The biggest advantage to having Dry Pipe Fire Sprinkler Systems is that there is no stagnate water in the pipes. This means that this is the perfect system for colder climates because it cannot freeze and rupture a pipe. A disadvantage to Dry Pipe Fire Sprinkler Systems is that they are fairly expensive. But, if your building is a freeze risk then the extra money is well worth it. It is much better to put in a more expensive, but trustworthy system than to have to worry about frozen and broken pipes.
