Abstract
A cryogenic valve comprises a valve body, a plug, an actuator, a kinematic chain comprising a driving member displaced by the actuator, and a transmission structure transmitting the movement of the driving member to the plug. A tubular bellows is arranged around the transmission structure and has internal corrugations protruding toward an interior of the tubular bellows Protections made of a material with a low coefficient of friction, are placed inside the tubular bellows on the internal corrugations. The protections are displaced with the internal corrugations along an axis of displacement when the driving member is displaced along the axis of displacement.
