Design de \u00e1rea de fluxo total, com pequena perda de carga, pouca tend\u00eancia ao ac\u00famulo de detritos, f\u00e1cil manuten\u00e7\u00e3o e outras caracter\u00edsticas.<\/span><\/strong><\/p>\n

A clapeta de borracha \u00e9 composta por chapa de a\u00e7o, barra de a\u00e7o e tecido de n\u00e1ilon refor\u00e7ado como substrato, sendo a camada externa revestida de borracha. A vida \u00fatil de acionamento da clapeta pode atingir 1 milh\u00e3o de ciclos.<\/span><\/strong><\/p>\n

Principalmente adequada para sistemas de abastecimento e drenagem de \u00e1gua, podendo ser instalada na sa\u00edda da bomba para evitar o refluxo e o dano por golpe de ar\u00edete \u00e0 bomba.<\/span> A v\u00e1lvula tamb\u00e9m pode ser instalada na tubula\u00e7\u00e3o de desvio da linha de entrada e sa\u00edda do reservat\u00f3rio, para evitar que a \u00e1gua do reservat\u00f3rio retorne ao sistema de alimenta\u00e7\u00e3o.<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
