Re: Questions about operation of pneumatic valves

We always use single solenoids unless we need the bi state feature. But yes, as you found out, bouncing a dual solenoid valve just right can cause it to shift. As others suggested, leaving the solenoid energized will stop that behavior. I have solenoids in the plant the stay energized for years without damage.
