Short answer is yes.

Depending on what you're using it for, this is possible, but it requires the use of the single solenoid valve upstream of the double solenoid valve. The Input into the single solenoid must be set on one of it's outputs (the other output MUST be plugged), and the output to the double solenoid comes out of the first valve's input. Next you must plug the release output of the single solenoid so that your piston stays in one spot. With all this rigged up, you can use the single solenoid to stop the flow of air to the double solenoid at any time, and with the press of a button, you can stop your piston wherever you want, no matter what direction it is doing.

This is only useful if you have a single solenoid valve sitting around gathering dust and you also have a Spike relay to use. Also, I don't believe the piston stays where it is once power is taken away.

E-mail me if you want some clearer directions, and once I get ours working totally, I'll know a little better (our problems are to do with the wiring of it, not the actual air flow).
