Principais vantagens da v\u00e1lvula borboleta tipo wafer (dupla excentricidade + veda\u00e7\u00e3o suave)
\nVantagens em estrutura e instala\u00e7\u00e3o
\nEstrutura de dupla excentricidade: O eixo da v\u00e1lvula possui dupla excentricidade. Quando a borboleta \u00e9 aberta em aproximadamente 20\u00b0, ela se desprende da sede da v\u00e1lvula. Isso reduz significativamente o atrito, requer baixo torque e proporciona uma longa vida \u00fatil.
\nConex\u00e3o tipo grampo: Sem flange integrada. Estrutura compacta, leve, economiza espa\u00e7o e permite instala\u00e7\u00e3o r\u00e1pida.
\nF\u00e1cil de instalar, desmontar e reparar: A sede da v\u00e1lvula pode ser substitu\u00edda independentemente sem desmontar a placa borboleta ou o eixo da v\u00e1lvula, resultando em baixos custos de manuten\u00e7\u00e3o.
\nDestaques de veda\u00e7\u00e3o e desempenho
\nVeda\u00e7\u00e3o bidirecional sem vazamentos: Veda\u00e7\u00e3o macia (EPDM\/NBR\/PTFE) + veda\u00e7\u00e3o tipo l\u00e1bio\/assento flex\u00edvel, veda\u00e7\u00e3o de grau bolha
\nVeda\u00e7\u00e3o din\u00e2mica: Quanto mais firme a veda\u00e7\u00e3o, maior a press\u00e3o. Ela compensa as varia\u00e7\u00f5es de temperatura e press\u00e3o.
\nBaixa resist\u00eancia ao fluxo + Excelente regula\u00e7\u00e3o: Caracter\u00edstica de fluxo percentual aproximadamente igual, fun\u00e7\u00e3o dupla de corte e regula\u00e7\u00e3o.
\nSem travamentos durante a abertura e o fechamento: Baixo atrito, baixo torque, adequado para aplica\u00e7\u00f5es manuais\/turbinas\/pneum\u00e1ticas\/el\u00e9tricas.
\nMaterial adequado \u00e0s condi\u00e7\u00f5es de trabalho.
\nMateriais de alta qualidade: Corpo da v\u00e1lvula em WCB\/304\/316; Placa borboleta em a\u00e7o inoxid\u00e1vel; Sede da v\u00e1lvula dispon\u00edvel em diversos materiais el\u00e1sticos para sele\u00e7\u00e3o.
\nAmpla aplicabilidade: \u00e1gua, \u00f3leo, g\u00e1s, vapor, meios fracamente corrosivos; -30\u2103 ~ 180\u2103 (dependendo dos componentes de veda\u00e7\u00e3o)
\nAlta durabilidade: Suporta dezenas de milhares de opera\u00e7\u00f5es de abertura e fechamento sem qualquer perda, sendo adequado para condi\u00e7\u00f5es de comuta\u00e7\u00e3o frequente.
\nCusto e rela\u00e7\u00e3o custo-benef\u00edcio
\nLeve e com \u00f3timo custo-benef\u00edcio: A 30%+ \u00e9 mais leve que as v\u00e1lvulas borboleta flangeadas, reduzindo a carga na tubula\u00e7\u00e3o e os custos de instala\u00e7\u00e3o.
\nLonga vida \u00fatil + Manuten\u00e7\u00e3o f\u00e1cil: Reduz o tempo de inatividade e o consumo de pe\u00e7as de reposi\u00e7\u00e3o, al\u00e9m de apresentar um baixo custo total ao longo de todo o ciclo de vida.<\/p>\n
