Cappuccino knob for Jura coffee machines

What is a steam or cappuccino valve knob

This is the control element used to open and close the flow of steam or hot water to the milk frother. It attaches directly to the valve spindle and is used to turn it manually when preparing frothed milk or hot water.

How to spot wear

• The knob spins freely or sits loosely on the spindle
• It is visibly cracked, broken, or missing part of the grip
• It is hard to operate, sticks, or won't hold any position
• Steam or water regulation is imprecise and the flow strength is hard to adjust

Why timely replacement pays off

A damaged or loose knob makes the valve difficult to control, leading to imprecise dosing of steam or water and can even cause steam leaks outside the frother. Timely replacement restores smooth and safe control of milk frothing.

How to choose the right part

Knobs differ in shape, mounting on the spindle, and appearance depending on the specific coffee machine model, so check compatibility in the product table before purchasing.
