A stainless steel wafer check valve with a PN20 rating is a specific type of check valve designed for use in pipelines with a pressure rating of PN20. “PN” stands for “Pressure Nominal,” and it is a designation used in European standards to indicate the pressure rating of a valve or piping system. PN20 indicates that the valve is designed to withstand a pressure of 20 bar or approximately 290 psi.
Stainless steel wafer check valves with a PN20 rating are commonly used in a wide range of industries and applications, including water supply systems, wastewater treatment plants, chemical processing, and industrial processes where preventing backflow and maintaining pressure integrity are essential.
