What is a valve flow restrictor
The flow restrictor is a small part built into the steam or water valve of a coffee machine, which regulates the amount of steam or water passing through the valve. Thanks to it, the output is even and predictable, which is especially important when frothing milk or dispensing hot water.
How to spot wear
When the restrictor becomes clogged with limescale, dirt, or gets damaged, the flow of steam or water changes. Milk froths unevenly, steam comes out weaker or, conversely, too forcefully, or the output becomes uneven or pulsing. In some cases, the valve leaks or water drips even when not in use.
When it's time for a replacement
A worn or clogged flow restrictor puts strain on the valve and can cause uneven dosing, which affects both the quality of frothed milk and ease of use. Replacing it in time restores smooth, stable flow and prevents further valve problems.

Flow restrictors vary in size and design depending on the valve type, so be sure to check exact compatibility in the product table before purchasing.
