Solenoid questions

[disb]

I am new, couldn't find much information on Chief Delphi or Google.

Here is my situation: I have 1 double acting, 10 inch stroke, 2 inch bore pneumatic cylinder and needs to generate a 60 psi. I have the cylinder, now I need to choose a solenoid valve to control the cylinder (and this valve will be controlled by PLC). To confirm with you guys, does it sound right that I should have at least 1 inlet, and at least 2 outlets? With this conclusion, I am planning to get a 4/5 port solenoid valve.

I understand 2 port valves, where there is just one inlet and one outlet, but how exactly does a 4/5 port valve work? Does it have to work with a manifold (because I am not planning to)? Any valves you guys recommend by say SMC (SYJ 3000 series?)?
