Y Type Bellows Seal Globe Valve

The Y type globe valve design reduces the flow resistance of the to a minimum.
The bellow seal valves non-rotating stem results in lower friction of all
moving parts and longer stem packing life. 
Y type bellows seal globe valve advantage
Why are Y type bellows seal globe valve less popular than normal bellow seal
globe valve？
1. They are all bellows seal globe valve bellow seal globe valves with double
seals (bellows +padding), normal globe valve only have padding seal. But their
body design is different, Y type bellow sealed 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 y type globe valve 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. Y type bellow seal globe valves are lighter than normal globe valve in open
and off.
Applications: steam system, hot oil system, hot and cold water system etc.
