|
|
|
Fire Suppression System
What is the secondary purpose of the orifices that are drilled through the flat middle plates in the hydrolic system of the dry type sprinkler? |
To vent operating pressure from the hydrolic control system when is return to auto or neutral.
|
|
|
Fire Suppression System
