A low-profile and small-size valve to a shut off a flow of fluid in a pipeline includes a frame, a tube, a moving part, a lever, an elastic part, a latch, and a trigger. The tube is movable with the moving part. The lever is rotatable around an axis. The elastic part can push the lever to rotate after the trigger pushes the buckle away from the lever to unlatch the lever and allow rotation. During the rotation of the lever, the lever pulls on the moving part, and the moving part pulls on the tube together to disconnect the tube from the pipe. The valve improves the convenience and efficiency of shutting off a flow of fluid. A pipeline and an immersion cooling system is also disclosed.

A surgical access assembly includes a cannula, a valve housing attached to the cannula, and a valve assembly positioned in the valve housing. The valve assembly includes a centering mechanism with a hoop and fingers, a ring with a flange at one end of the ring, a retainer having first and second discs, a guard having a frame and flaps attached to the frame, and a seal with petals attached to a support. The guard is at least partially disposed in the first disc and the seal is at least partially disposed in the second disc.

A valve sealing device for a tilting-armature valve, including: a sealing body having a first surface configured to close in a fluid-tight fashion a valve seat and/or an opening in a valve; and a retaining body which is arranged on a surface of the sealing body which is opposite the first surface, and is configured to secure the valve sealing device in and/or on a cutout in a valve, in particular in a cutout in a tilting armature of a tilting-armature valve, in particular in which the sealing body and/or the retaining body is essentially cylindrical in shape. A related method to make the valve sealing device and a tilting-armature valve that includes the valve sealing device are also described.
