General Description:
The bellows sealed globe valve uses a closed bellows that can be stretched and compressed to replace the packing, which can effectively prevent external leakage caused by packing loss. It is generally used for the transportation of highly permeable media, such as valves on hydrogen systems, as long as the bellows is not damaged, there will be no leakage.
Design Features:
Zero stem emission,Graphite stem packing secondary seal,Welded seat ring or integral body seating surface,5,000 cycles bellow without failure
Application:
