Advantage
ANSI Standard Bellow Seal Globe Valve function is same with Din globe valve.
1, They are all bellow seal globe valves，they are all have double seals (bellows +padding), normal globe valve only have padding seal. But their body design is different, you can check their pictures.
2, Disc with scraping effect, so it has a longer service life.
3, The inside seals bellows are all made by stainless steel 321, which is more corrosion resistant and have a longer service life.
4, bellow seal globe valves are lighter than normal globe valve in open and off.
