    We're hooking up solenoids to a low-pressure air supply–1-4psi. The 10 bellow units receiving pressure each have a volume of approx 1 liter and will achieve up to 0.3psi. We want to inflate and deflate the bellows quickly. We want to be able to

    I am not sure there is enough information here to suggest a specific valve. However, you should be able to use a small direct acting valve. The Clippard EV is a great valve and may work for this application.Anyone would need to know the size of th

    The bellows are approximately the size of a 1.5liter nalgene bottle. They are to fill or empty in about one second, going from 0 to 0.3psi. Do you know where we could find a pressure and volume vs fill time chart or formula? I’ve seen them, but on

    Maybe I misunderstood what you were originally asking. It sounded like you were filling the bellows with a valve, then dumping to atmosphere using the bellows as the exhaust mechanism.Now that I have a clearer picture of what you are doing I can
