The E61 Flow Control Device allows you to manually adjust the water flow in your E61 brew group to profile your extractions. This custom component is a stainless steel needle valve, which allows the user to vary the amount of water flowing through the group. Variable flow control allows for lengthy pre-infusion for more even saturation and extraction of your espresso.
Like Profitec's existing mushroom, the flow control device is made from stainless steel to resist corrosion. The resulting changes in pressure are reflected by an included gauge that installs on the front of the group. The E61 Flow Control Device can be installed on any Profitec Espresso machine with an E61 brew group.
