    Ok so here is what i want, a valve that opens depending on its signal voltage. I know the input will be a voltage, and the output will be the variable actuation of a valve from closed to open depending on the voltage it recieves (ex. 0-5v is closed to open) what I dont know is how to make the logic in between the two. I work on cars for a living so i understand input-logic-output because it is a process used on all modern automobiles but i dont know how to make my own past the input and output. If anyone understands what I am saying and can point me in the right direction the help would be appriciated. Remember I am a technician not an engineer this is new waters for me.

    Do some research on transistor switches,especially on MOSFET.

    What is flowing through the valve?

    Google proportional control valve.

    What kind of valve? Proportional valves are expensive, there are cheaper motorized versions out that resemble spigot types, just motorized instead of manual.

    If it is a simple rotary valve like the throttle in a model engine, then you can use a model servo. Any similar rotary valve that requires less a than a full turn should also be adapted to that solution. Isn't the accelerator-throttle in cars electronic?

    The application is a valve to control exhaust flow through a turbo, I need the valve to open according to engine speed.

    Then such application is not for discussion on AAC and this thread is closed.

    The owners of All About Circuits have elected not to host discussions of automotive electrical system modifications/enhancements due to safety concerns, the potential of legal ramifications and the possible circumvention of vehicle regulations at the state and federal level.

    This thread is against the AAC forum rules, Chapter 6, as seen here:

    This can be found in our Terms of Service (ToS)

    Automotive modifications of any kind are strictly forbidden. Therefore, this thread will be closed.

    Please try to understand the reasons behind this action, and feel free to browse and use the forums.

    Good luck.
