Abstract

Una válvula de mariposa que comprende un disco de válvula (16) ubicado en un paso de flujo (14) dispuesto en una carcasa (12) que se puede acoplar a un asiento (22) dispuesto en la carcasa (12) y caracterizado por que el disco de válvula (16) y la carcasa (12) cooperan uno con otro, cuando el disco de válvula (16) ocupa una posición cerrada, con el fin de definir un vacío anular (28) que se extiende alrededor de la periferia del disco de válvula (16) con una posición separada del asiento (22), un puerto de entrada (30) y un puerto de salida (32) que se comunican con el vacío (28) con el fin de permitir el suministro de producto de sellado al vacío (28) para formar un cierre hermético entre el disco de válvula (16) y la carcasa (12).
