As we all know, for the use of electric ball valve, it is suitable for the chemical industry. The first thing is to make it achieve the maximum corrosion resistance on the product, and it naturally meets this requirement because of the improvement in materials during production. Another aspect is the use of its products, which can also be applied to petroleum. For petroleum, its biggest product use is to achieve the advantage of anti-static. 　　

3、 Assembled from scratch
1. Clean and check the removed parts, and replace the valve seat, bonnet gasket and other sealing elements.
2. Assemble in the reverse order of disassembly.
