How to select the type of electric ball valve when encountering high temperature medium. Generally, the operating temperature of our electric ball valve is - 20 ℃ - 120 ℃. At this temperature, it can be sealed with rubber rings. This is normal temperature, but when encountering high temperature media, how to select the type of electric ball valve? Let me tell you why we can use VSSJA-2 electric ball valve under high temperature and pressure?
Because the steel products themselves are more resistant to aging, corrosion and high temperature than the products made of valve materials, and the sealing ring of electric ball valve is changed to packing for sealing, the bearing temperature will naturally reach higher. We all know that when the sealing material used for electric ball valves in high-temperature and high-pressure pipelines is the valve sealing ring, it is easy to leak, and the valve sealing ring is easy to deform when subjected to high temperature, resulting in irreversible plastic deformation. So how to use electric ball valves in chemical pipelines, especially when the pipeline medium is high-temperature corrosive medium, The graphite packing seal ring developed by the designers of our company based on years of experience has a very good sealing effect. When the electric ball valve is manufactured, it is made of high-quality anti-corrosion materials. The seal ring is made of flexible graphite packing with anti-corrosion paint, which provides triple protection for the pipeline and effectively achieves corrosion resistance. Our corrosion resistant electric ball valve is mainly used in petrochemical pipelines, desulfurization and denitrification pipelines, seawater desalination pipelines and acid and alkali transmission pipelines. Through the above brief description, we hope that it will be helpful for you to choose the model and material of the electric ball valve in the future. If you have any questions about the expansion joint, please call Hengchang Pipeline. We have special personnel to introduce you the detailed knowledge about the electric ball valve.
