Zusammenfassung: | A valve for a cryogenic-fluid device has a valve seat, separate from the valve housing and of a different material, secured to the housing by shrink-fitting into a recess thereof. The readily replaceable seat has a high structural strength and preferably has been subjected to an anodizing treatment. The valve seat projects axially into the path of fluid passing through the nonclosable valve port. The valve housing is made of easily weldable materials, e.g., aluminum and aluminum alloys, and flanges for pipe connections are welded to the valve housing. |
