Or would I be better off with a design like this?
Spool type valves usually have 3 pistons, instead of 2. Any reason for this?
Planning a build, quick question.
I'm in the planning stage of a build, and have a quick piston valve question. I want to keep the piston as light as possible, but want it to work properly. Would this work? Plan on building an over under Pneumatic, barrel sealer.

Are you using this piston inside of a tee fitting? If that's the case, have a look at my piston valve from my hybrid.
For a pneumatic, you don't necessarily need the long rod and seal at the left end of my valve, although I imagine it would help the pilot dump quicker. You would just place your fill valve and dump valve behind the piston.
In your diagram, you appear to have an o ring around the front of the piston, near the sealing face. For it to open properly, air needs to be able to push by the front of the piston and exit the barrel.
