On the copper side, this fitting is 1/2". This means that standard type M or L copper tubing with fit inside of it. It likely would not work with the valve you described. You would probably need to sweat this elbow to a small piece of copper that is connected to the valve.
Yes, they can.
This 3/4" x 3/4" elbow will allow 3/4" copper pipe to fit inside its copper end.
With this elbow you make your connection to a copper pipe, with the part H120750 which can be found on our website here: http://www.pexsupply.com/HydroPEX-H120750-3-4-PEX-x-3-4-Copper-Fitting-Brass-Elbow-4947000-p , you make the connection to a copper fitting.
No, this is PEX to copper pipe (sweat).
