You can use the pilot operated check valve. Install it on the cylinder port that connects to the normally closed side of the directional valve. Then, the cylinder will extend (or retract, depending on how you have it set up) as long as you're pressing the trigger, and it will stop when you release it. To retract, apply pressure, which would have to come from another valve, to the pilot port of the check valve. This setup unfortunately requires two valves to operate one cylinder. The pneumatics kit would be more useful if it had a better selection of directional valves.
