Introduction
Y Type Bellows Seal Globe Valve main for steam, hot oil pipeline. It is generally used on pipes that require no flow loss.
Advantage
Why are Y type bellows seal globe valve less popular than normal bellow seal 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, Y type bellow seal globe valve body more better for flow control. It has no flow loss,but a little expensive than normal bellow seal globe valve.
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.
