I bought a valve for which the seller has posted a picture that shows that the male side of the valve goes into shower hose and the female side of the valve goes into shower handle:
However, I am questioning if that picture is correct, because the filter net that came with the valve can be put only on valve's female side:
And best to my knowledge, these filter nets are there with purpose to stop debris from entering valve shutoff mechanism that could cause fail-open situation. Which clearly is not the case here.
So my question is - Is the picture posted by seller incorrect? Can I install the valve the way I think is correct instead by using a wall mount shower head that has the opposite-gender thread compared to a handheld shower head?:
