The 255 series is characterised by robust cast steel and a wide range of variants for a variety of industrial applications. These safety valves cover nominal diameters from DN 15 to DN 100 and offer a consistent performance, function and design concept that enables both vertical and horizontal installation. The series is particularly easy to maintain thanks to its low overall height and the option of using a full-nozzle design. Ideal for fast-reacting processes in chemical plants.
For US standards, the ANSI version is available with ASME B16.5 flanges and API 526 valve stem lengths, which facilitates integration into corresponding systems.
