I can't find anything like that number on Emerson's (Alco) site.
But why not just pick a different TEV to suit your application, conditions and capacity?

That sounds like it's a constant pressure expansion valve I found the A series valves in the johnstone catalog # 198 pg 1286. Or here's a link http://www.johnstonesupply.com/corp/...t_Code=B12-512 I'll bet they could help ya out.
