Standard 1/4" anti-vacuum valve with a stainless steel plunger, which lasts longer as the steel cannot get coated with lime.

This valve will have failed, if lime builds up inside causing it to stay open - you would hear a constant hiss if it is stuck open.

It's a quick and cheap fix - use PTFE tape to make the seal - see below.

Why buy?

  • Steam escapes from the valve when the machine is on - constant hissing. Typical of older machines or when the boiler has lime buildup.
  • No steam from the steam wand, but hot water comes from the coffee groups.

Technical details:

  • Size: 1/4"
  • Material: Brass body made of brass CW510L (OT57) - low lead content | Stainless steel plunger 
  • O-ring seal made of HNBR
  • O-ring end-stop in PTFE

Made in Italy
