Lennox 16U86 Service Valve

I'm looking for a Suction Line Service Valve for a Lennox XP19-036-230-02 . I don't know the part number. Was told by our repair guy that it's obsolete and he can't get the part (assuming from Lennox). Please let me know if you have the correct part. 214-548-5419. Thanks.

R104519-02 is the one for XP19-036-230-2 and here is the link of this part, please check if you can use this:
