1st-line Equipment E61 Grouphead Flow Control Regulator

Unlock the ultimate extraction precision with the E61 Grouphead Flow Control Regulator Kit, featuring a solid stainless steel mushroom and integrated pressure gauge. This premium aftermarket modification is known to fit ECM, Profitec, and Izzo espresso machines originally equipped with a stainless steel mushroom, transforming your standard prosumer setup into a powerful manual pressure profiling station.
By replacing the factory component with this heavy-duty, food-safe stainless steel assembly, you gain additional control over water flow rates during extraction. The internal, finely threaded needle valve allows you to taper pressure up or down seamlessly—mimicking classic lever machines or implementing low-pressure pre-infusion to maximize sweetness and clarity from your favorite single-origin coffees or light roasts.

Key Features & Benefits

  • Premium Stainless Steel Construction: Unlike chrome-plated brass alternatives, the solid stainless steel mushroom may provide additional corrosion resistance, long-term durability against scale buildup, and excellent thermal stability.
  • Real-Time Pressure Feedback: Equipped with a highly accurate, front-facing M6 threaded pressure gauge, providing pressure readings right at the grouphead for precise, repeatable shots.
  • True Flow Profiling: Take complete manual control over the extraction phase to minimize channeling, extend pre-infusion, or save unevenly ground shots on the fly.
  • Compatibility: Specially designed for integration with premium E61 grouphead espresso machines, known to be compatible ECM, Profitec, and Izzo models.

What is Included in the Box?

  • 1x Stainless Steel E61 Flow Control Mushroom Assembly
  • 1x Fine-Control Handle / Knob
  • 1x High-Precision Grouphead Pressure Gauge
  • 1x Stiffer Lower Pre-Infusion Spring (Essential for bypassing built-in pre-infusion and unlocking 100% manual valve control)
  • Necessary Teflon Seals and O-Rings

    The manufacturer has stated stainless, but manufacturers do reserve the right (as we have leared many times) to change without any notification to us.
    2. Can you please confirm the gicleur filter screen length and o-ring sizes, are they the same as a Lelit Bianca i.e. 11mm long screen and MC044 o-ring 6.07x1.78?

    Sorry, the manufacturer does not provide measurements, nor do we take measurements as they can change in the future without any notification from our supplier - then future customers would point the the blame on us for different measurements.
