描述

forged bellow gate valve dimension and drawing

Performance advantage
Bellow is the key part of bellow sealed valves.which is welded to both the valve bonnet and valve stem,with automatic roll welding. The melal bellow can keep the stem part 100% no leakage.
Double seal design(bellows packing).Bellow form a metal seal to prevent leakage,and packing can provide seal if the bellow failed.

DESIGN FEATURE
Bolt bonnet(BB)
Welded bonnet(WB)
Outside screw and yoke(OS&Y)
