Functional Principle Design variations • CONTIFLOW = Válvula de amostragem com bucha de PTFE• CONTIFLOW TRF = Válvula de amostragem com bucha de PTFE e macho revestido em PFA(recomendada para indústria farmacêutica)• CONTIFLOW TRF-A = Válvula de amostragem com bucha em PTFE, corpo e macho revestido em PFA (recomendada para indústria farmacêutica e fluídos corrosivos) Conexão do frasco • adaptador em PTFE para frasco de laboratório padrão ISO. Recomendo para fluídos de baixa e media toxidade. • Suporte retrátil: recomendado para troca rápida de frasco e em casos de alta temperatura. • Sistemas de agulhas: totalmente fechado para frascos de laboratório com septo. Sistemas de agulhas tipo NH e NH-S com diâmetros internos de 2 a 6mm. Recomendado para aplicações altamente tóxicas.

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.
