DN1-9J459-AA
The vacuum solenoid valve is a key control element in vacuum systems. Its main functions include: Switching Air Paths: controlling the on/off state of vacuum lines via electromagnetic force, changing airflow direction. Regulating Vacuum Level: precisely controlling gas flow to maintain stable system pressure. Metered Charging: injecting a specific amount of gas into the system when needed. Preventing Backflow: in automotive applications, it can prevent oil or gas backflow from contaminating the system. The vacuum solenoid valve is also used to control air conditioning flaps, adjust idle speed, manage door lock systems, etc.
