[DeTomaso] A/C expansion valve

[jderyke at aol.com]

Tom, mfgrs stopped using the final screen filter when they went to r-134a. It is less efficient and the screen slightly slows down freon flow. You can r&r your old one after thorough cleaning if you wish.
 There are two different length bourdon tubes for the deicing switch so I'm not surprised that your new expansion valve is different.

   Since R12 is no longer made there are no new expansion valves made
for
   it. I have been using the R134 valve with R12 for the last 10 years
and
   it works fine.
   Good luck with yours, I am sure it will work fine
also.

     I ordered a new expansion valve from Wilkinson and received it
today.
     I noticed it was stamped 134a and that the capillary tube is
longer
     than the original valve.  I plan to continue to use R-12 so my
  
question
     is will the new valve stamped 134a work with R-12?
     I also
noticed that the new valve did not come with a filter screen.
   I
    
suppose I could use my old one but why wouldn't it come with a new
    
screen?
