    What is your question? Are you asking what a 128 air valve is? Do you have a manufacturer?

    I am not sure what a 128 air valve is but SAVs (Solenoid Air Valves) are used for a lot of different functions in a pneumatic control system. One of their main uses is to reposition actuators (usually to the off position) when a fan or pump are turned off.
