e) limescale build up.
We cannot guarantee this will fit every E61 grouphead.
E61 Grouphead Flow Control Device with Pressure Gauge
Key Details & Compatibility
- Universal E61 Design: Designed to install directly onto most standard E61 groupheads.
- Verified Brand Compatibility: Confirmed to fit and function on Rocket Espresso models, including the Rocket Appartamento and Rocket Appartamento TCA. By extension, it should be compatible with other standard E61 Rocket models (such as the Cronometro or Mozzafiato).
- Core Functionality: Features a manual needle valve to regulate water flow (enabling long pre-infusion and custom extraction profiles) paired with a grouphead-mounted pressure gauge to monitor extraction pressure in real time.

Hello and sorry for the delay in responding to your question. We believe that the mushroom is made of a combination of plated brass (top) and stainless steel (bottom), but have not been able to confirm this with the manufacturer. While we believe it should work, this assembly has not been tested with the ACS Vesuvius.

So far, other customers have not had issues. As stated, we can never guarantee fitment on any parts.
Hi All, hope all is well. My valve for the flow control is not behaving properly, at 8 o clock it opens up to 7 bars which gives me very very little room to play with. My setting is as follows: valve to be fully shut at 9'o clock and fully opened at 1' o clock (counter clockwise) I am beginning to thing the tension on the spring that it came with is not where it needs to be. If I were to replace the spring where would we buy the springs from ? Any thoughts please ? much appreciated!

Please run a descaler through the grouphead and allow to sit overnight. The chance of a bad spring is not likely at all. Build up with interfere with the gicleur and needle portion of the valve.

The grouphead gauge measures resistance in the portafilter. It will not register if there is no backpressure created with a portafilter. You can test with a blind filter. If still an issue with the blind filter, either that portion of the grouphead is blocked or a particle entered the gauge and blocked it.
