I went through this about 4yrs ago. My Westendorf loader has this valve but Westendorf no longer use it so they dont have parts.I did a search on google and and found a website for Danforce fluid power. The dealer I went through was in the Saint Louis, Mo area. Danfoss wont sell to individuals. I ended up talking to one of the factory reps who figured out which PB sleeve I needed and sent it to the dealer and the dealer shipped it to me. I will keep digging around and see if I saved any of the info.
