boundary conditions - directional valve, basic help

I am writing here to enquire information about way of applying boundary conditions at Directional valve. I modeled internal path into valve and inlet and outlet pipe.
Information about valve:
min/ max pressure 3-10bar
I want to determine delta p
and my Question is how to apply BC in Ansys CFX 11, I have noticed that i we have opportunity to choose
in inlet section:
Total Speed, Comp. speed, static pressure, total pressure, mass flow rate
in outlet section:
averaged static pressure, normal speed, static pressure, mass flow rate. eventually what relative pressure I have to assume?
And now I have a problem, because theoretically i can determine total speed from Q, but I don't know what to apply at outlet.
I am aware that it is obvious for most of you but i am really beginner so if someone can help I will be grad.

have you done Tutorial 20: Fluid Structure Interaction and Mesh Deformation ?
Top 4 tips
1. Knowledge is everything and Ignorance is dangerous.
2. Understand your limitations and try to eliminate them.
3. Get yerself a bike and hoon the chuffer. You will soon learn why dogs like to hang their heads out the car window.
4. Please before asking any questions on how to run simulations in CFX, go though all the tutorials
