CMA/Astoria Argenta Steam Valve Knob

Replacement steam valve knob for Astoria and Wega machines, sized for the standard 6 x 6 mm valve shaft used across the Argenta line and other models.

SPECIFICATIONS

  • Fits 6 x 6 mm shaft

COMPATIBILITY

  • Fits: any model Astoria or Wega machine with a 6 x 6 mm steam valve shaft

INSTALLATION

DIY-friendly, but can require significant force to seat, see Pro Tips.

PRO TIPS

  • Check inside the knob before installing, some units ship with an extra spring already installed, and doubling up will prevent a proper fit.
  • These can be extremely tight to install; a rubber mallet is often needed to tap the knob fully onto the valve shaft. Tap squarely to avoid cracking the knob.
