A solenoid valve is an electromechanical valve for use with liquid or gas. The valve is controlled by an electric current through a solenoid coil. Solenoid valves may have two or more ports: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.:
Do you think it makes a different what material the solenoid valve is? I was looking at the valves here http://www.electricsolenoidvalves.com/ but Im not sure which one to use with the Arduino setup?

Solenoid valves are great specially when you use them on pneumatic valves. ;

Dont think it matters too much – http://www.ebay.co.uk/itm/High-quality-DC-12V-1-2-Inch-Electric-Solenoid-Valve-fit-Air-Water-Oil-/281080216548?pt=AU_Business_Industrial_Industrial_Supply_MRO&hash=item4171afbbe4 for example should be fine. The one I used was about that price.
You wil of course need a relay – something like http://www.instructables.com/id/SEEED-Studio-Arduino-5V-Relay-module-Digita/
I purchased an Ciseco relay – but they dont seem to do that one anymore.
