Y692VB Series Vacuum Breaker

Y692VB Series Vacuum Breaker The Y692VB Series vacuum breakers are used in applications where an increase in vacuum must be limited. An increase in vacuum (decrease in absolute pressure) beyond a certain value registers on the diaphragm of the Y692VB Series, moving the disk away form the seat. This permits atmosphere or a positive pressure to enter the system and restore the controlled vacuum to its original pressure setting.
