Abstract
A valve apparatus () for use in sterile fluid transfer or isolator systems has open entry () and exit () sides and a passageway () for fluid between the entry () and the exit () sides. The entry side () is connectable to an opening () of a vessel or pipe () and the exit side () is connectable to downstream processing by means such as tubing, a vessel or a pipe. The entry side () includes a rupturable seal () blocking the open entry side (). Valve () also includes an actuator () attached to a piston () which moves within the valve (), the piston being connected to the seal so that on movement of the piston, the seal is torn free from the entry side thereby allowing fluid gain entry to the valve () and to pass along the passageway () between the open entry () and exit () sides to downstream processing.
