Ascaso Anti Vacuum Valve  €11.90

Description:

Standard 1/4" anti-vacuum valve with a stainless steel plunger.

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.

You may need a new valve if:
- 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
