The E61 Flow Control Upgrade gives you ability to change the flow of water in the brew group to customize your own profiles during extraction. The valve is made of stainless steel with a needle design, which permits users to vary the water volume through the group head. Variable flow control opens possibilities for lengthy pre-infusion for better water saturation and extraction during the espresso preparation process. This device's stainless steel construction will resist corrosion. The added pressure gauge reflects changes in pressure, and sits on the group head for easy viewing. This E61 Flow Control Upgrade can be installed on any ECM Espresso Machine which has an E61 group head. Note: This flow control device was designed by ECM/Profitec and is not guaranteed to work on other machines produced by other manufacturers.
