I would want to use this on a boat, I have a winch with a directional valve and a motor on the stern, I also have a capstan with a motor and a directional valve on the bow, am I correct in assuming that this valve would allow me to use one or the other, isolating the one that is not selected, in case I bust a hose? I already have a relief valve in the system, should it be before this selector valve?
A: Yes. This valve would allow you to isolate either valve on the system for operation or repair. It is always best to have the relief in line before this valve, just in case some physical or operator failure occurs which leaves the selector spool unshifted and blocks pump flow.
do you have air actuators that can be fitted on this valve to move the spool back and forth
A: We do not, no.

Can the position be changed when the circuit is under pressure. I would like to use it as a circuit divider and be sure that one side is not operational when the other is on. Or i should be better to use a 3 way valve?
A: Yes, this can be shifted when under pressure. If a pump flow is being shifted, be aware that if the spool does jam in the centered position while shifting, there is no internal relief for the pump flow and could cause damage to the pump.
