Solenoid Valve Recommendation
 

I'm looking for a 4port, 120psi rated, 12-18 volt solenoid valve for a robot project. What are the best manufactures to look at and which are the most reliable.

I'm looking for an 850psi two way solenoid valve that's cheaper the Burkett 5404.

Re: Solenoid Valve Recommendation
 

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.

If you can, find a pneumatics supplier locally, and walk in. Since you're only looking for one, they may have a floor model or incomplete package that they'll sell cheaply. Also, you'll be able to discuss your needs and hear their recommendations.
