Description Pipe Systems in chemical and petrochemical plants are usually purged with flushing fluids such as water, steam, air or nitrogen. After the flushing process a safe depressurizing is necessary. For this purpose AZ developped the type “BMH” with features easy and simple in operation: The special plug form, with positive overlap, allows during the quarter turn to close the flushing fluid supply and then to depressurize the flushing hose automatically. This ensures maximum safety for operators and environment.The valve is conform to TA-Luft.


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.
