This would be consistent with the Brand Valves that I have experience with except that you have another fixed port. I believe the T port would needed if you were using older tractor where the oil "must go somewhere". Then the oil would come in on port "P" and out on Port "A"to the orbit motor as you have it but the excess which needs to go somewhere would return from port "T". That port would be Teed in with the return from the orbit motor.

With that arrangement, the valve would be splitting the flow with some going out on Port A to the orbit motor and the excess back to the tractor on Port T.

With your current arrangement, the valve is just controlling the oil going out on Port A to the orbit motor since the tractor does not require a return path for the excess.
