| Short Description: | As its name suggests, cryogenic valves are designed to be used in very cold applications. They are thus most popularly used by companies that work with Liquefied Natural Gas (LNG) or Compressed Natural Gas (CNG). For instance, the oil and gas industry frequently uses cryogenic temperature ranges starting at -238 degrees Fahrenheit (-150 degrees Celcius). Additionally, some gasses aren't labeled 'cryogenic' because of their temperature, but rather because they require more than a simple pressure increase to compress their volume. Cryogenic valves are built to help transport and store such cryogenic gasses safely and efficiently.Cryogenic valves differentiate from other standard valves in the modern market due to their ability to be fully functional both in temperatures as low as -320 degrees Fahrenheit (-196 degrees Celcius) and at pressure ratings as high as 750 psi. |

|
| Working Type: | Cryogenic valves are kept in a natural closed position to keep cryogenic gasses or other medium secure and safely contained. A cryogenic valve is generally designed to react to high pressure which pushes the valve into the open position to allow the gas or other media to flow readily through. |
| Application: | - Liquefied natural gas (LNG)
- Liquefied petroleum gas (LPG)
- Liquefied oxygen
- Liquefied hydrogen.
- Air separation industry
