The term "DN50 valve" refers to a valve with a nominal diameter of 50 millimeters. "DN" stands for "Diameter Nominal," which is a standard measurement used in piping systems to indicate the size of the valve or pipe. DN50 valves are commonly used in various applications, including water and gas systems, to control the flow of fluids. The specifications may vary depending on the valve type and manufacturer.
