Fisher™ Y696VR Series Vacuum Regulators
Y696VR Series vacuum regulators are used where a decrease in vacuum must be limited, such as between a tank and vacuum source to control vacuum in a tank.
A decrease in vacuum (increase in absolute pressure) on the diaphragm moves the disk away from the seat, allowing a higher vacuum source to return the system to the setpoint.
