Principe de fonctionnement : le blocage du flux inverse du milieu se fait en appuyant sur le joint souple de l'obturateur de la vanne sur son siège, sous l'action d'un ressort et la pression du flux inverse.  La vanne est ouverte par une différence de pression dans le débit du milieu dans la direction souhaitée, tandis que le volet de la vanne bouge, compressant le ressort.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cspan\u003eParamètres de poids et de dimension des soupapes de contrôle DNOVA 402A 16 bar Matériau du corps - fonte GGG50, brided\u003c\/span\u003e\u003c\/h4\u003e\n\u003ctable border=\"1px\" cellpadding=\"0\" cellspacing=\"0\" class=\"table_materials_karto4ka\" style=\"width: 144.299%;
