Solenoid Valve Recommendation

[AdamHeard]

The voltage of the solenoid is generally separate from the specs of the valve; it's commonly a separate piece on higher end valves. (You can get 12VDC. 24VDC 110VAC, etc...).

I've used SMC, festo and MAC valves, and all are quality products.

You didn't specify a desired flowrate, that really is the great variable here. Everyone will have a valve that meets that psi and voltage, they just get bigger and more expensive with the flowrate.
