Wicovalve 606: Swiss Degassing, No Filter

The Wicovalve 606 is a round, one-way coffee bag valve that releases CO2 from freshly roasted beans while locking oxygen out. It is the unfiltered version of our premium Swiss degassing valves, engineered for clean pressure relief and reliable aroma protection on whole bean coffee packaging. Stocked in our UK warehouse for next-day UK delivery when you order before the cut-off.

Perfect for: roasters fitting valves to plain or unvented bags, packing lines applying valves in-house, and any whole bean format that needs to off-gas without going stale.

FAQ

What does a coffee bag valve do?
It lets CO2 from freshly roasted beans escape the bag while preventing outside air from getting in, so your coffee stays fresh and the bag doesn’t balloon.

Does the Wicovalve 606 have a filter?
No. The 606 is the unfiltered model. If you need a filtered valve, choose the Wicovalve 616 instead.

What pressure does it operate at?
The valve opens within a 3.0–7.0 mbar range to release degassing pressure safely.

How are they supplied?
In boxes of 10,000 valves, held in UK stock for fast dispatch.
