Electric Valve part question

I am looking for an electric valve to control a water supply to an automated coffee maker i am building. I bought this one: http://www.ebay.ca/itm/Electrical-Pneumatic-4V110-Solenoid-Valve-Coil-AC-220V-With-Lamp-/300707507215?pt=Pneumatic_Hydraulic_Valves_Parts&hash=item4603906c0f&_uhb=1#ht_1328wt_1397

But I have no idea how to control it with an electric signal. Would this one be more appropriate? http://www.ebay.ca/itm/Electrical-Pneumatic-4V110-Solenoid-Valve-Coil-DC-12V-/261141713258?pt=LH_DefaultDomain_0&hash=item3ccd42516a&_uhb=1#ht_1296wt_1397

Or maybe this one : http://www.aliexpress.com/store/product/2P025-DC-24V-Normally-Closed-Pneumatic-Solenoid-Valve-2P025-06-G1-8-Wire-Lead-Coils/907092_475518886.html

Thanks guys!

The first one requires 220V AC so it's not easy (or safe) to work with.

The second one is just the coil, not the whole valve.

The third one might work. They don't specify the working voltage but the coils they show are marked 24V DC.

That is described as a pneumatic valve which probably means it is suitable for turning a pressurised air system on, or off. Not necessarily suitable for water.

Scroll down and it says it can be used for Air/Water/Oil/Gas.

For a more domestically accessible valve you can look into the valves used on dishwashers/etc. Most are 110V AC but you could still drive that easily enough with a relay.

This is what Kuerig uses. Caveat: I've had to replace two of these in two Kuerig coffee makers because of leaking. - Scotty
