You use a compressor? I have never used one on a bike tube (except that one time I exploded a tire when I was a kid). I would imagine that may have something to do with your problem. I would invest in a good floor pump; preferrably one with a built in pressure gauge. You may find that your problem goes away (unless the valve quality does in fact make a difference, that is.)
