I experienced a slight problem with the expansion valve list above that did not manifest itself on the bench, but only showed up after an extended run in the coach. The valve above does not appear to bleed the pressure between high side and low side after the compressor turns off. This results in the compressor trying multiple times to start against too high of a head pressure. This is not good for the compressor.

I found another valve that does work well, and is much much cheaper.
