What is the difference between a deluge valve and a dry valve?
A deluge valve and a dry valve are both types of control valves used in sprinkler systems, but they have distinct differences in their design and function.
A deluge valve is designed to open immediately upon receipt of a signal from a fire detection system, allowing water to flow freely into the sprinkler piping. It is typically used in deluge or pre-action sprinkler systems where rapid water distribution is crucial.
On the other hand, a dry valve is used in dry sprinkler systems, where the piping is filled with air rather than water. The dry valve prevents water from entering the piping until a fire occurs and the valve is activated. This design helps to prevent freezing in cold environments and reduces water damage in the event of a false alarm.
