PT-Diagram

A pressure-temperature diagram with multiple curves representing different lining materials, annotated with details like temperature scales in Celsius, pressure in bar, and labeled functionalities such as "vakuumfest/vacuum proof.

The specified values depend on the respective application (medium). Operating temperatures under -20°C only with body material 1.4408 or low-temperature steel. Hight pressure resistance / temperature resistance on request, e.g. PN 40.

Sleeve: There are different sleeve materials / compounds available.
