valve + actuator

[altoid3000]

I was looking at a data sheet for valve + actuator for flow control. Pneumatic actuation. The data sheet specified Air consumption (6.7 cu inches etc. ) for different models. How is air consumption defined for this application? Is it the amount of air reqd. per actuation? At what pressure do I need the air ?

It has Electroless nickel plated brass body. What is electroless?
