Even though the threads are at 1.5 Inch's, Have a look down the bore of the tap.
It is just under an inch in diameter.

It's a bit hit and miss there hey.
I had a ball valve like yours on my spray bar but it was causing low pressure up the top end of the slotted bars.
I removed it and just running 1-1/2 hose into the 1" poly fittings to the spray bar and it fixed the problem immediately.
I don't really need the valve anyhow.
