Abstract

"CONJUNTO DE VáLVULA COM SEDE INTEIRIçA". Trata-se de um dispositivo de sede de válvula constituído de um material plástico de suficiente rigidez mecânica para fixação estável a um conjunto de haste, que atua como um condutor para transmitir uma força acionadora dentro de um corpo de válvula, enquanto que possuindo a resiliência necessária para proporcionar uma superfície de vedação, e combina tal superfície de vedação e parte condutora numa unidade contígua, em que a interação entre o dispositivo de sede de válvula anteriormente citado e o elemento vedante correspondente dentro do corpo de válvula controla o fluxo de fluido e a pressão de fluido.
