Description
1. Overview of Imported Low-Temperature Shut-off Valve
The low-temperature shut-off valve, also known as LNG shut-off valve, liquid nitrogen shut-off valve, liquid oxygen shut-off valve, liquid argon shut-off valve, and liquefied natural gas shut-off valve, is specifically designed for managing low-temperature liquids such as LO2, LN2, LAR, and LNG. These valves are essential for storage and transportation systems, offering:
- Flexible operation
- Reliable sealing performance
- Suitability for other cryogenic media
VTON’s range of low-temperature globe valves includes the following options to meet diverse requirements:
- Short-sleeved low-temperature globe valves
- Long-sleeved low-temperature globe valves
- Stainless steel low-temperature globe valves
- Welded low-temperature globe valves
- Flanged low-temperature globe valves
- LNG-specific low-temperature globe valves
These valves are extensively applied in industries such as ethylene production, liquefied natural gas facilities, LPG/LNG storage tanks, air separation equipment, petrochemical tail gas separation systems, and pressure swing adsorption oxygen production equipment.
