Introduction
Liquid Ammonia Stainless Steel Bellow Seal Globe Valve ，as the name implies，it can be used on liquid Ammonia.
Why liquid Ammonia pipeline Choice Stainless steel bellow seal globe valve？
1, As Ammonia is highly corrosive, Material should choice stainless steel.
2, As Ammonia is poisonous, Disc seals need soft, use PTFE as seals to increase the sealing performance.
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.
