The series of flanged safety valve 455 captivates with its consistent concept of capacity, function and design.
The high capacity of the entire series from DN 15 up to DN 100 is unique in the sector of flanged safety valves.
By using exclusively high-quality materials with outstanding media resistance and the option to secure the tightness towards the atmosphere on a high level with a backpressure compensating bellows, this safety valve is suitable for nearly all applications.
The pressure range extends from 0.2 to 20 bar and the operating temperature range is extremely wide from -270 to 400 °C.
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.
