Design Features

Características construtivas

  • Extensas superfícies de vedação(bucha de PTFE) garantem a estanqueidade absoluta
  • Substitui os spools com duas válvulas – menor custo
  • Recomendada para aplicações severas
  • Longa durabilidade e com possibilidade de reajuste do macho (sem parar o processo)
  • Várias possibilidades de montagem das válvulas de inspeção/dreno e alívio
  • Alternativa técnica as válvulas de sapata retrátil – maior durabilidade e menor custo
  • Firesafe design conforme API 607 / ISO 10497 (somente para atmosfera)
  • Aprovação TA – Luft – livre de emissões fugitivas

PT-Diagram

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.
