How to Connect Refrigeration Access Valves

How to Connect Refrigeration Access Valves

No matter you want to install the access valves on the fridge compressor or install the combined access valve and copper filter drier, most customers maybe choose a welding connection.

Today I want to show you a new technology, called “No welding connection” technology.

The principle is to use cold processing and deformation to achieve a good connection between different metal materials.

Such as the copper access valve with copper pipes, or aluminum pipes, etc.

You can use the suitable refrigeration press-fitting and progress tool, and the special sealing liquid, no need for fire, no need for high temperature, just crimping them together.

And you don’t need to worry about the leaking situation, cause we do a lot of testing before we send it to you, bursting test, cold and hot alternate test, salt fog test, and vibration test.

The bursting pressure is 30MPA, working pressure is 5-7MPA. The testing temperature is -50℃~+150℃.

The most advantage is: No welding connection provides you with the greatest high-efficiency connection method, it can save 80% more time than welding!

Even though you are a freshman, you can easily operate it very quickly and easily.

For detailed info for no welding connection and how to connect the access valve, you can check the using instruction on the refrigeration press-fitting page.
