NFPA 16 Standard For The Installation Of Foam-Water Sprinkler And Spray Systems Practice Test

The foam-water dry pipe system releases water to open a valve known as which type of valve?

Wet pipe valve Dry pipe valve Deluge valve Check valve

Correct Answer:

Dry pipe valve

Explanation:

In a foam-water dry pipe system, water is kept out of the piping by a dry pipe valve. When a sprinkler head is activated, air in the valve’s air chamber escapes and the drop in pressure allows the valve to lift, releasing water into the dry pipe network. Foam concentrate is then introduced into that water downstream to create the foam solution. The other devices don’t perform this action: a wet pipe system already has water in the pipes, a deluge valve is used to open all sections in a deluge system, and a check valve only prevents backflow.
