Abstract
"VáLVULA DUPLA COM EXAUSTãO TRANSVERSAL". Sistema de válvula de controle tendo um alojamento definindo uma primeira entrada, uma segunda entrada, uma primeira saída, uma segunda saída e uma exaustão para definir uma válvula dupla intrinsecamente segura. O sistema de válvula de controle dupla da presente invenção ainda inclui um par de passagens transversais de exaustão que elimina a necessidade de dispositivos de cronometragem complicados.
