    I have a valve bank of seven valves that needs replacement.
    I've found a suitable replacement, however it runs on 24v instead of 12v.
    The valves are non latching and draw 31.25 ma of current each.
    I need to design a circuit that allows the 12v signals to control the new 24v valves.

    I am hoping for an IC based solution. I do not need a circuit built from bjts.
    I only need to build this once, so making it low cost isn't really a requirement.
    Simplicity is best. Any thoughts on what IC or ICs I should use?

    Let your 12 VAC fire a triac that allows a 24 VAC transformer send power to the valves. Seven resistors, one transformer, 7 triacs.

    Sorry, I should have specified, these are DC solenoid valves.

    Thanks, that is exactly what I need. Pretty basic stuff, guess I need to hit the books a little more.

    The world keeps changing. That's why there are websites for the nut cases that keep up with these things.
