I need a lightweight plastic spool valve >100psi >10mm

I am looking for a lightweight plastic spool valve that will handle up to 100 psi with push on barb connectors for 8 or 6 mm hose. It would be nice if it could be actuated from either end. It is for a prototype so it would be great if I could get this from an existing manufacture.

As it is a prototype the above is a wish list and is therefore flexible.

I have done plenty of searches on Google and on this site with no satisfactory result.

Any leads would be appreciated.
