The Valterra 1/2" check valve # P23415LFVP fresh water backflow preventer has an arrow stamped between the threading and the nut. It can be difficult to see, if you don't look closely. You should install the backflow preventer with the arrow pointing in the same direction as the water flow. I have attached a photo that clearly shows the correction direction.
