The Y690VB Series vacuum breakers are used in applications where an increase in vacuum must be limited. When there is an increase in vacuum (decrease in pressure) beyond the setpoint on the diaphragm, it moves the disk away from the seat. This permits atmosphere or a positive pressure to enter the system and restore the controlled vacuum to its original vacuum pressure setting.
The Type Y690VBM has a control line connection and O-ring stem seal for external pressure registration.
