Abstract
"VáLVULA DE FLUXO EM EXCESSO". Várias válvulas de fluxo em excesso melhoradas são mostradas, onde o fluxo em torno de uma porção de manutenção de ímã do corpo de válvula é geralmente irrestrito, para redução da perda de pressão através da válvula. A válvula, preferencialmente, também é formada separadamente de sua sede de válvula, para redução da complexidade da válvula, e permitir que ela tenha menos resistência ao fluxo. A sede de válvula pode ser provida como uma parte separada, ou pode ser provida no conduto.
