New ballcock question

While tying up the plastic ballcock arm in the loft, I rather stupidly snapped it. I went out and got a brass one, which seems to be a much stronger replacement, so no big deal. However, the new one is a lot noisier than the old one. Again, that wouldn't be a big deal, but when the tank is close to its full level, and the valve is near to closing, the noise starts to fluctuate. I imagine that it has created some kind of resonance in the water, and that adjusting the mains water cock will get rid of it (I only open it about a single turn). But I have a question about the new brass valve. The water comes out of a hole drilled into the bottom of the valve body. Okay, I know it's got to come out of somewhere, but since it just dribbles and splashes all over the place, I'm wondering if perhaps there shouldn't at least be some kind of nozzle to attempt to direct it (like the old plastic one had)? Am I supposed to buy something else to finish it off? I'm thinking that this might be contributing to the noise.

Or a small hole near the top of the tube to allow air back in.

My MiL had one like that - the feed into the loft tank went through a 90 degree bend a couple of feet from the tank, then went across the loft for 10ft, all unsupported. I tied the bend to a rafter with a bit of string, and that damped the vibration enough to shut it up.
