Re: selector valve
I think I may have it now. P1 restricts all A ports so P2 would be for flow on B ports. i would think the flow would be:
Coil 1 off P1 to C1A, P2 to C1b
Coil 1 powered Circuit 1 off other circuits can be used
Coil 1 and 2 on P1 to C2A, P2 to C2B
Coil 1 and 3 on P1 to C3A, P2 to C3B
