95 740 - A/C expansion valve

Hello.

I am new to this forum, but not new to BMW's. I currently have a 95 740i and am in the middle of a complete a/c rebuild. I have run into a problem trying to get the expansion valve off. I have disconnected the lines that run from the firewall to the valve, but I still can't get the e-valve off. Is there a locking tab on the opposite side of the valve?

If anyone out there knows I would really appreciate the help.

Thanks in advance.
