hmm, well today when i worked on our pnuematics we encountered difficulties with the valve and had to take about 4 hours just to find leaks in the pnuematic system and put teflon on all of our brass plugs and everything else that seemed to be leaking.

i would check to see if any other part of the pnuematics system is leaking before you try to ask for a replacement or anything... make sure that it's the part that isn't working.

good luck
