// Why Buy From The Bag Broker
Sealers, valves, tin ties and spares sit in the same UK warehouse as the bags they are used with — one order, one delivery, and a team that can tell you which one fits your packaging.
Held in our UK warehouse, not shipped from overseas to order — so there is no long wait for a machine or a part.
Order online before the daily cut-off and it leaves the warehouse the next working day, with the bags on the same order.
Compatibility with our box bottom, side gusset, stand up and flat pouches is stated on every product — check the seal width against your bag.
Not sure which sealer, valve or spare fits? Ask before you order — we have supplied flexible packaging since 2004.
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.

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.
