Why the one way coffee valve must have oil inside?

Today we receive some client's special question about one way coffee valve.

The client asked: whether Color Suns one way valve have oil inside the valve?

This is a very important and professional question about one way valve.

Most of clients choose the valve only will check their specification, their application.

For the specification of one way valve, you will check whether its size same with your before one. Whether its size can install or work with your valve applicator machine.

For the application, clients most will check what is the different application of the one way valve, for bean or for powder.

But the professional clients, they will check whether the one way valve have oil in it.

Why we must check and ask whether the one way coffee valve have oil in it?

Let me explain:

First, the one way valve called one way, it is mean that, it can only release the CO2 out of your package bag, but it can prevent the oxygen entering into your package bag. That is cause this valve will be called one way valve.

One way degassing valve, coffee valve — one way coffee valve

Second, how to make it only release CO2 and can not enter oxygen? That is depend on the sealing oil inside of the valve. The sealing oil can prevent the outside oxygen entering into the package bag through the one way valve. Of course, if you check your one way valve, and there is without any oil in it, so your valve only can call two valve valves. There are most of this kind of valve in the market.

Third, the valve made it in one way valve not only depend on the oil, but also the structure of valve inside.
