Liquid Ammonia Stainless Steel Bellow Seal Globe Valve

Liquid Ammonia Stainless Steel Bellow Seal Globe Valve has dual-sealing characteristics, achieves zero leakage in the fields of liquid Ammonia.

Product Description

The stainless steel bellow globe valve produced by AFBV Valve, due to its dual-sealing characteristics, achieves zero leakage in the fields of heat transfer oil, steam, chlorine, liquid ammonia, and other working conditions, making the bellow seal valve widely applicable.

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 sealed globe valves are lighter than normal globe valve in open and off.
