How To Check The Material Of The Butterfly Valve

The material of the butterfly valve is the most important thing. If the material is not good, the manufacturer has always been unreliable. Today the butterfly valve manufacturer will tell you how to check the material of the butterfly valve.

1. Chemical and spectral analysis

The use of chemical analysis to determine the content of various elements in the butterfly valve material is a long-standing method, and this method can be said to be very reliable based on long-term use. Spectral analysis means that the material of the butterfly valve emits spectrum under high temperature and high energy excitation, so the material of the butterfly valve can also be determined by spectral analysis.

2. Spark identification

When grinding metal materials, sparks are often generated due to intense friction. The identification of the butterfly valve material is based on this method, polishing it, and identifying the composition of its material by distinguishing the characteristics of its sparks.

3. Section

The butterfly valve sample is cut, and the content of various elements in the valve material can be distinguished from the characteristics of the color and crystal grain on the cross section, but this method often requires people with a certain amount of metal material manufacturing experience to do it.

The above is the knowledge shared by butterfly valve manufacturers. I hope it will be helpful to you. If you want to know more, please contact us as soon as possible.
