Washing machine valve size determination?

Could someone please tell me by pictures what size valve is this?

In coming from pipe and outgoing to washing machine.
I think they are 1/2 incoming and 3/4 outgoing.





There are thread on incoming pipe.
Are these threads on the pipe and there is an adapter soldered to pipe.

What kind valves should I replace with? I have these https://www.homedepot.com/p/Tectite-...WMAV/302161124

I have 3 questions.

Q1. Are ball valves any better in terms of functions (not leaking) and longevity over globe vales (what I currently have)?


Q2. New Valves are sharkbite valves https://www.homedepot.com/p/Tectite-...WMAV/302161124. They require smooth pipe. How should I do it? Should I buy a female adapter like these https://www.homedepot.com/p/Everbilt...HD34/100347144

and these https://www.homedepot.com/p/1-2-in-B...-005/203073898

Q3. If yes then what size should I buy? 3/4 incoming water side and and 1/2 towards sharkbite valve? Do I need to buy a new box to get a better access to pipe?

additional enlargements....

 

In the one picture where a little bit of the pipe can be seen.... it sure looks like copper pipe.
That would mean that valve is soldered on. It doesn't look like the valve will unscrew off.

 

Thanks Pete:
I did notice that. I seems like actual pipe is 1/2 inch and an adaptor with threads has been soldered to pipe. Valve is fitted on that adaptor/connector. Plumber will replace these and other valves. I am buying all the supplies.

I need to know what size valve I need incoming from pipe and outgoing to washing machine.

Do I need an adaptor, like the one I posted link? there are all kinds of adaptors available.

 

I'm not familiar with that valve. It looks like all one piece.
Let the plumber supply the parts.

The copper pipe is 1/2" and the hose fitting is 3/4" .

 

Get this valve for washing machine. 1 lever turns off water.

I agree with pugsl, I only install those one-handled shutoffs for washing machines. No one will ever take the time to turn off the old style valves.

It'll all have to removed and re-soldered anyway, so why not upgrade!
