Purpose of valves for airbag setups

[abadsvt]

I have ordered all of my air ride setups. I told suicide doors my situation and they sent me what they felt best for my needs. Anyways i recieved 8 valves. What is the purpose of the valves? I noticed that they are all have some cylinode on top. There is 2 wires coming off each valve. How do i hook them up and what do i hook them up too? Can i tie some of the wires together in a series or do i have to run each wire. Any comments would be greatly appreciated. Thanks Josh
