For corrosive conditions such as strong acids, strong alkalis, and those containing chloride ions, Viti offers 316L and 2205 duplex stainless steel valves. The valve stems have undergone special surface treatment, and valves made of special materials such as Hastelloy, Monel, and titanium can be customized. The sealing surface adopts a hard seal surfacing cobalt-based alloy or an imported PTFE/PEEK soft seal solution. The packing system complies with the ISO 15848 low dissipation requirement and can be made of FDA/USP VI-level certified materials. It is particularly suitable for fine chemical, pharmaceutical and food industries that have strict requirements for sealing reliability, dissipation control and medium purity.
With its "material-structure-sealing" three-in-one adaptability, Viti has accumulated a good reputation in the harsh working conditions of stainless steel valves.
Summary and suggestions: When purchasing stainless steel valves, one should, based on the characteristics of the medium (corrosiveness/temperature/solid content), pressure rating and installation environment, give priority to examining whether the manufacturer has a mature selection plan for the corresponding material and project cases in the same industry. Comprehensively evaluate its qualification certification, quality control system and after-sales network to avoid making decisions solely based on price.
