The one I saw was a Micro-mite metering valve.  They are pretty costly, but 
they are very nice.  Incidentally, Neil Frank gets the credit for having 
found this valve, altho he did find it by accident.  My guess is that the 
other letters in the part number refer to how it attaches to the input and 
output devices.
