Explore the core advantages, applications, and selection guidelines for ASTM A216 WCB Y-Type Strainers. Learn how this high-temperature, high-pressure cast steel strainer safeguards industrial pipelines and extends equipment lifespan.

In the case of limited installation space, it should be noted that the gate valve can rely on the medium pressure to tightly close the sealing surface, so as to achieve the effect of no leakage. When opening and closing, the valve core and the sealing surface of the valve seat are always in contact and rubbing against each other

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.
