ABSTRACT:
A valve device for use in a transfer line for sterile fluid production material that communicates fluid from a supply pipe for the sterile fluid production material by opening and closing the flow path for the operating line including a first valve operatively connected to the supply pipe and a second valve operatively connected to a delivery pipe for at least communicating fluid to processing stages for the above-mentioned sterile fluid production material. A first valve plug is operatively mounted within the first valve. A second valve plug is operatively mounted within the second valve. A steam inlet pipe and a steam outlet pipe is positioned substantially perpendicular to a common axis of the first and second valves and on a line dividing substantially in half the gap between facing first and second valve plugs of the first and second valves and opening on opposite sides of the gap so as to form a chamber between the first and second valve plugs.
