This 3/4 in. Brass PEX Barb x Barb Ball Valve will be my main shut off valve in my house. It will be in an interior wall behind a wall panel.

How can I secure this valve within the wall so it doesn't move around when the valve is turned on & off?

Generally you would just secure the PEX with some pipe clams near the valve and that would be good enough. The valve just hangs there in mine and I usually grab a pipe with one hand when I turn it.

  • This seems avoidably prone to stressing the barb fitting attachment to the PEX. Maybe not an issue for valves which are rarely used.

  • If you're worried about the valve shifting you could brace it with wood alongside.

You can use a "drop-ear" valve, which would look like this:

The "ears" are meant for mounting the valve with screws.
