Fireproof and anti-static ball valve is a kind of natural gas, artificial coal gas, liquefied gas, city gas and non-corrosive gas pipelines, with anti-static, fireproof device, that is, in the ball and valve stem, valve stem

As critical components in modern fluid control systems, the internal precision of ball valves directly impacts system reliability. This guide demonstrates ASME B16.34 compliant disassembly procedures using a DN50 stainless steel floating ball valve as example.

Before installing the clamp-on electric butterfly valve, butterfly valve manufacturers need to carefully check the use and performance specifications of the gate valve. If left unchecked, the following common failures can occur:

Surface color whitening treatment: Stainless steel flange in the process of processing, after winding, tying, welding or after artificial surface fire heating treatment, produce black oxide skin. This hard gray-black oxide skin is mainly composed of two EO4 components, NiCr2O4 and NiF, which were previously removed by strong corrosion methods of hydro fluoric acid and nitric acid. However, this method is costly, polluting the environment, harmful to the human body, corrosive, and gradually eliminated.
