E61 Infusion Valve

The brass machining on this valve is precise, and it seated perfectly into my group head without any leaks. My shots are now flowing with a much steadier pressure during the pre-infusion phase.

The pre-infusion control is noticeably more consistent now — my shots are pulling evenly every time. Installation was straightforward, and it fixed the dripping issue I'd been dealing with for weeks.

Finally got around to replacing the original valve, and this one controls the pre-infusion flow much more evenly. It's a direct fit for the E61 group, though I wish the packaging had included a new o-ring. Still, it's working perfectly after a few shots.
