Are you here for the updated valve with a custom-engineered proportional ball opening for vastly improved heat output tunability on C3 CenterFlow Coolant Heated Bars? You're in the right place! It's at the top of the dropdown.

• If you haven't yet, click the "Ball Valve Info" tab to read what all the hype is about
• Reminder - the valve you already have might already be the Proportional optimized one, even if you got it last year - all valves with extra white on the handle tip (like in the pic) DO have the gradually-adjustable internals. It is what's provided with all new heated bars.
• Inversely of course, all valves with handles that are plain black (save for the C3 logo) were manufactured with the off-the-shelf ball, which gives a bit more of an on-off effect.
• Also, don't forget the super helpful tips in the "Push-to-connect Guide and Assembly Kit Walkthrough" tab when you go to do the installation.
• If you don't still have your Assembly Kit, you might consider picking up a new one for a few bucks.
