Does the drain off valve need to be screwed in tight

Hi Experts
I am replacing a leaking drain of valve. However when I screw it in to the radiator it does not tighten in suitable position. I.e. drainage point facing up and the screw to open valve against the wall so you cannot reach it. If I leave it in suitable position it is not tight.
Any ideas how I can get it to tighten in a suitable position or is it OK loose (I assume not).
I am restricted with space so this is the only type.of valve that will fit
