  • complete chain of documentation for all parts
PT-Diagramm
A pressure-temperature diagram with multiple lines, each representing different sleeve materials such as ptfe (virgin), ptfe (graphite), and ptfe (glass) from an industrial supply company in

Operating temperatures < -30°C and > 220 °C have to be checked and approved by AZ according to the operating conditions.

Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M).

1) For operating temperatures below -10°C low temperature / austenitic steels are required.
2) Sleeve: There are different sleeve materials / compounds available.
