PT-Diagramm-2015-GB 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.


Standard body materials • forged steel 1.4301, ASTM A240/A182 Standard plug materials • forged steel 1.4301, ASTM A240/A182 (304) • forged steel 1.4541, ASTM A240/A182 (321) other materials on request
