Understanding PN, Class and temperature
Quick answer
No. PN and Class are different rating systems. Allowable working pressure depends on the standard, body material and temperature. Do not equate their numerical values.
Are PN and Class equivalent pressure ratings?
No. PN and Class are different rating systems. Allowable working pressure depends on the standard, body material and temperature. Do not equate their numerical values.
Technical specifications
Ranges cover different configurations within the product family. Maximum pressure and temperature do not apply simultaneously; verify the material and pressure–temperature rating for the selected configuration.
Selection starts with the application
Size alone is not enough. We consider medium, temperature, differential pressure, connections and sealing requirements together.
Let’s specify the right valve.
