Design Features
Características construtivas
- Fluxo pleno com seção transversal circular
- A vedação não tem contato com o fluido (após operação)
- Alta capacidade de estanqueidade conforme API598
- Segurança total para os operadores e meio ambiente
- Coeficiência de vazão garantido durante toda a operação
- Não há possibilidade de erro operacional
- Retorno seguro do “volume residual”
- Combinações econômicas (sem reduções)
- Aprovação TÜV
O príncípio básico do dispositivo de segurança consiste de que uma seção transversal mínima (Amin) está garantida durante a fase de comutação entre a válvula de segurança 1 e a válvula de segurança 2. Esta área de passagem garante o coeficiente de vazão mínimo do sistema e com isso a segurança do vaso de pressão..

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.
