I am having a ton of fogginess today thinking of a way to switch a couple On-Off valves with the hardware I'd like to use. When I say 'On-Off', I mean the valves pictured below, where applying voltage to the Open terminal opens it, and applying voltage to the Close terminal closes it. It will stop at any time (last position is the maintained position; I have other circuit components that will allow for this.)
I would like to use a 3-way (SP3T) selector switch to select which configuration to operate: Valve 1, Valve 2, or BOTH.
I would like to use a single, momentary switch in the configuration of On-(Off)-On, or where the center is the normal state (off, nothing energized) and either side is momentarily energizing the OPEN or CLOSED motion of the Selected valve as mentioned above.
Is this even possible? I can't seem to wrap my brain around it today. I've done similar circuits before, but they had the benefit of hot (L) also being controllable with upstream logic, so in a way it was easier controlled.
UPDATE: Link to datasheet. (Pg6, Figure 1 is the particular wire diagram I'm referencing.)
