Introduction
Angle Bellows Seal Globe Valve main for steam, hot oil pipeline，it is mostly be used on right-angle pipeline.
Advantage
In fact，the angle bellows globe valve is the same as the ordinary bellows globe valve, but the application scenarios are different. The angle bellows globe valve is generally used at the right angle of the pipeline (in some special working scenarios). so customers buy Not many.
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 application are different.
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.
