Vibiemme group anti-vacuum valve, original — triangular pin, 27.3 mm length
Part no. ET-100054
Original group anti-vacuum valve for Vibiemme (VBM), with a triangular pin and an overall height of 27.3 mm (14 mm inner pin). The three-sided pin touches the body less, builds up less scale and sticks later than cylindrical pins. Made for Vibiemme groups; some Victoria Arduino models share the architecture — confirm the sizes.
Yes, it is the original Vibiemme (VBM) group part, such as the Domobar. Some Victoria Arduino models with the same architecture can use it; if so, confirm the sizes.
Why the triangular pin?
It touches the body at only three points, so it builds up less scale and sticks later than a cylindrical pin; air and steam also pass more freely.
What are the sizes?
Overall height 27.3 mm and a 14 mm inner pin. It is best to check against the current part.
What are the failure signs?
A hiss or continuous steam leak at the valve, poor steam at the wand and the machine stalling as it heats, often from scale.
Is it original? Do you ship?
It is an original VBM part. We ship to Portugal and across Europe; For availability, request a quote.
