O trajeto interno do fluxo \u00e9 otimizado, com perda de press\u00e3o m\u00ednima. O curso de abertura e fechamento do disco \u00e9 muito curto, permitindo o fechamento r\u00e1pido quando a bomba \u00e9 desligada, evitando o forte golpe de ar\u00edete e proporcionando um efeito silencioso. A v\u00e1lvula \u00e9 utilizada principalmente em sistemas de abastecimento e drenagem de \u00e1gua, combate a inc\u00eandio e HVAC, podendo ser instalada na sa\u00edda da bomba para evitar o refluxo e o dano por golpe de ar\u00edete \u00e0 pr\u00f3pria bomba.<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
