e-61 flow rate control kit

Description

This e-61 Flow Control Device allows you to adjust the flow of water in your brew group to manually 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 and post infusion for more even saturation and extraction of your espresso.

Do they make a difference? Yes they do!
