Zibo Weiheng Valve Co., Ltd., February 28th: When users choose gas butterfly valves, material is often an important consideration. So, how can users identify the material of gas butterfly valves on their own without relying on manufacturer instructions?

Weiheng Valve Line Sealed Gas Butterfly Valve

1. Spectral and chemical analysis

Spectral analysis refers to the emission spectrum of butterfly valve materials under high temperature and high-energy excitation, so spectral analysis can also be used to determine the material of butterfly valves. The use of chemical analysis to determine the content of various elements in butterfly valve materials has been a method for a long time, and this method can be said to be very reliable based on long-term use.

2. Spark identification material

When polishing metal materials, sparks are often generated due to intense friction. And the identification of butterfly valve materials relies on this method, polishing it and identifying its spark characteristics to determine its material composition.

3. Sectional material

Cutting the butterfly valve sample can distinguish the content of various elements in the valve material from its color, grain and other characteristics on the cross section, but this method often requires someone with certain experience in metal material manufacturing.

The gas butterfly valve produced and developed by Zibo Weiheng Valve Co., Ltd. can be made of stainless steel materials such as 304 and 316, and there are even more materials available for the sealing surface. Weiheng valve adopts a spherical line sealing structure in the treatment of the sealing surface, making the seal more tight and the switch more flexible. The line sealed gas butterfly valve of Weiheng Valve has a good reputation among many using enterprises.
