Abstract

"VáLVULA DUPLA HIDRáULICA". Sistema de controle de válvula em que as válvulas principais são atuadas e desatuadas através de operação de válvulas piloto. A atuação das válvulas piloto causa a atuação das válvulas principais, o que permite que pressão de fluido seja feita sair do sistema de válvula de controle. As válvulas principais devem se deslocar dentro de um período de tempo predeterminado a fim de impedir uma condição de erro. Uma câmara de distribuição armazena uma quantidade predeterminada de fluido para definir um período de tempo em que as válvulas principais devem se deslocar.
