Product Description

 

Product Description

Introduction:

Cryogenic globe valves are essential components in industries handling ultra-low temperature fluids, such as LNG (liquefied natural gas), air separation, chemical processing, and aerospace applications. These specialized valves are designed to maintain reliable sealing, frost resistance, and structural integrity in extreme cold environments (typically below -40°C/-40°F, even down to -196°C/-320°F for LNG).
To ensure safe operation, cryogenic globe valves use austenitic stainless steel (e.g., 316L), brass, or special alloys to prevent brittleness, along with extended bonnet designs to isolate the stem seal from cold fluid. Their low-emission packing and precision-machined seats minimize leakage, while fire-safe and anti-blowout stem designs enhance safety. Proper material selection, rigorous testing (per BS 6364, ISO 28921, or MSS SP-134), and strict quality control make them indispensable for cryogenic systems requiring bubble-tight shutoff and long-term durability.

Product Advantages:

1.Tmperature Performance: Valve body and stem materials maintain good toughness and strength at extremely low temperatures.

2.Reliable Sealing Performance: Metal or soft sealing structures ensure zero leakage in cryogenic conditions.

3.Anti-Freeze Design:Extended bonnet design prevents cryogenic media from reaching the packing area.

4.Flexible Operation: Supports manual, electric, or pneumatic operation to meet various working conditions
