A coupling assembly (10) is reconfigurable among three states. In a disconnected state, a spring-biased lock indicator (20) is in a first lock indicator position, and the lock indicator includes a restriction member (40) that in the first lock indicator position retains an actuator in a first actuator position such that a valve is in a closed position and a locking pin is in a retracted position. In a connected/valve-closed state, the lock indicator (20) is in a second lock indicator position in which the restriction member (40) permits movement of the actuator (30), but with the actuator (30) still being in the first actuator position such that the valve is in the closed position and the locking pin (46) is in the retracted position. In a connected/valve-open state, the lock indicator (20) is in the second lock indicator position to permit movement of the actuator (30), and now with the actuator (30) being in the second actuator position such that the valve is in the open position and the locking pin (46) is in an extended position to lock a second coupling assembly to the coupling assembly to form a unisex coupling connection.

A connector assembly includes a first and a second component. Each of the components including a connector body, a valve, a handle, a handle lock, and a connector lock. The handles open and close respective valves. Each of the handles has locked and unlocked positions. The handle locks prevent or inhibit the respective handles from being moved between open and closed positions. The handle locks in unlocked positions enable the respective handles to be moved between open and closed positions. The first and second components are configured to be releasably assembled with each other. The connector locks in their respective closed positions assist in preventing or inhibiting the disassembling of the first and second components.

A quick-connector comprises a first body portion, a second body portion, and a ball valve. The first body portion defines a first fluid channel. The second body portion defines a second fluid channel. The second body portion is coupled to the first body portion such that the first fluid channel is aligned with the second fluid channel. The first fluid channel and the second fluid channel form a fluid channel extending through the quick-connector. The ball valve is positioned in the fluid channel extending through the quick-connector. Movement of the first body portion and the second body portion relative to each other causes the ball valve to move between a flow position and a sealed position. In the flow position, the ball valve allows fluid to flow through the quick-connector. In the sealed position, the ball valve prevents fluid from flowing through the quick-connector.

A testing cap for a valve body includes a base configured to releasably attach to the valve body and to cover an opening in the valve body. The opening is configured to receive a valve cartridge and the base covers the opening in place of the valve cartridge. The testing cap includes a structure extending from the base. The structure is configured to be oriented relative to the valve body in a first orientation and a second orientation. The structure allows fluid to enter the valve body through an inlet port in the valve body and exit the valve body through an outlet port in the valve body when the structure is oriented in the first orientation. The structure covers at least one of the inlet port and the outlet port when the structure is oriented in the second orientation, thereby preventing fluid flow through the valve body.

Various embodiments provide a connector for the sterile transfer of a liquid medium from a container to a bioprocess engineering system. The connector has two coupling devices. The coupling devices each have a housing and a control element which is adjustably mounted in the housing interior and forms a channel. The channel extends from a control element inlet opening to a control element outlet opening. The housings are able to be mechanically connected to one another and have a fluid inlet and a fluid outlet. The fluid outlet of one housing and the fluid inlet of the other housing overlap. The control elements are each adjustable from a starting position, into an operating position, in which the control element inlet opening is fluidically connected to the fluid inlet and the control element outlet opening is fluidically connected to the fluid outlet.

A joint includes a male module and a female module capable of docking with each other. The male module includes a core rod and a sliding cylinder that is slidably sleeved on an outer periphery of the core rod. A first valve port is disposed in the sliding cylinder, and the core rod is provided with a piston head that is in hermetic fit with the first valve port. The female module includes a valve body and a piston. A first channel is disposed in the valve body, the piston is slidably disposed in the first channel, and a second valve port that is in hermetic fit with the piston is disposed in the first channel.

The present disclosure provides a communicating structure applied to a first communicating body and including a door assembly. The door assembly is assembled in the first communicating body, and includes a door movably connected to the first communicating body, and a connecting structure allowing movement of the door. The connecting structure includes an actuating portion, and the door is provided with a connecting portion. The actuating portion is for acting on the connecting portion or performing a lever operation on the connecting portion so as to move the door.
