If your machine has an E61 group head, YES this product should work.
With the Quick Mill E61 group head flow control device, you can manually profile your extractions by adjusting the flow from the closed position (0-bar) to full pump pressure, usually 9-bar. This E61 flow control device can work on many common machines like the ECM flow control device does.
The flow control device can be installed in machines that are equipped with standard E61 groupheads. With just a couple of tools, your coffee machine will be able to vary the amount of flow using the stainless steel needle valve now installed on your E61 group. This needle valve is the main working component that allows the user to vary the flow of water to your coffee where you’ll have full control of saturation and extraction of all that you love about your espresso!
The Flow Control Kit replaces the E61 spring with a stiffer one that does not compress unless manually activated to drain excess pressure through the exhaust. This is so that you do not have to manually manage the pressure of controlling the flow restriction while simultaneously compensating for the pressure difference as that pre-infusion valve compresses.
