Vacuum Actuators

Vacuum actuators commonly work with both valves and throttles, its general function remains the same. There is a chamber that create vacuum pressure (negative pressure) in a vacuum actuator. While the air is drawn out by the vacuum source, it creates a vacuum (negative pressure) inside the actuator; the outside pressure (positive pressure) acts on the diaphragm of the actuator. This pressure is greater than the spring inside the actuator and overtakes it to allow it to open, sending pressure to the throttles.
