Help with timing controls

Hi,

I'm new to this forum, so hopefully this is in the right place.

I am using an Ni 6009 with labview 2012 to turn on/off 4 valves. I am to the point where I can manually turn the valves on/off in the front panel, but what I need to do is have a timed cycle. 

What I need to have is for example:

1) Valve 1 open, Valve 2 open, Valve 3 closed Valve 4 open.

2) Wait x amount of seconds.

3) Valve 1 open, Valve 2 closed, Valve 3 closed Valve 4 open.

etc.

How can I make this happen?

I'm fairly new to this program, so any help would be greatly appreciated.

This is what my block diagram looks like, it is attatched.
