Hirsbrunner produced some horns that the valves were made of some sort of plastic material. These valves are very prone to problems because as temperature fluctuates the valve material and the metal casings expand at differents rates messing with the close tolerences between the two. I suspect that you would have a similar situation with teflon valves.
