5/3 way proportional directional control valve VPWP work?

[Guffrus]

Never heard of one of those before but there are video guides and many resources online it seems.

Im not quite sure what you are having a problem with specifically, they appear to 'work' using solenoids to open and close the valves.

How the wider system it is integrated into 'works' would presumably depend on how it is connected up, what signals are being used to control the flow etc and how those signals are generated etc.

Why do you need to know? / What specifically are you asking? / What is the context?
