I won a valve off ebay...NORGREN K71EA00...5 ports one solenoid on each end. The solenoids say 24vdc 0.25A...at Big Lots I bought a whole bunch of 16V 10A 120V AC part number C905 (says- converts 120 volts to 16 volts used by a door chime) low voltage transformers. Can I use these transformers to run the valve?

Thanks in advance

AC can be converted to DC by running it through a full-wave rectifier and then putting a largish capacitor across the DC side to smooth out the resulting bumps. (Look at this site for a basic idea..) The real question is whether 16V will be enough sufficiently to drive the 24V valve....

Make sure you get the correct polarity. Look for this symbol on the adapter

and be sure that you connect it to the valve correctly. AC doesn't matter but DC does. Radio Shack has adapter's for DC that you can change the polarity of the center pin voltage, or you can cut the wire and test it with a voltage meter.
