Plumbing question

[Salty]

I am going to install a washing machine combo valve and I am not sure about something. This is the kind that has 1 lever that controls both ball valves and both hot and cold are turned on or off at the same time. It is a 1-piece cast brass valve.
The hookup is either iron pipe thread on the outside or 1/2" copper sweat on the inside.
If I make the connections with any type of union using the existing pipes as they are, it will cause the valve to be right up against the block wall, unless I do a lot more plumbing with more elbows.
Ok, the question is:
Would it be advisable to make the connections without a union and just solder a short stub from the in-line Tee to the valve.
Crude drawing below!

You could slightly bend the pipes as they come down the wall to give you more room at the union. You might need to take some clamps off, and put some shims/blocks behind the pipes. For example the pipes are only 1/4 inch from the wall at the ceiling, but they should be able to bend out several inches in about 4 feet at the valve, give or take some depending on the type of pipe.

Thanks for the advise Ric. Actually, there is enough room there as it is, if I don't use unions. I didn't want to move the sink out away from the wall and the bottom of the supply lines hook up to the slop sink. If I move the lines away from the wall I'd have to elbow them back to the sink.
I think I can remember enough about my past experiences and do a good soldering job. So, I think I'll try a direct solder connection.

I solder once in a blue moon and would occasionally come up with a drip. I now use the paste solder/flux combination instead of just flux (still use solder off the roll) and it gives a leak-free joint every time. It's not elegant, but it works and the joints look good.

Was thinking about having to move the sink and drain, was only thinking of supply lines.

If your going to solder remember to take out the rubber fittings, and such. Don't want melt things inside.
