Middleeast valve is a topmost Cryogenic valve supplier in UAE. We supply to cities like Egypt, Riyadh, Turkey, and Dubai. It is a specialized type of valve designed to handle extremely low temperatures, typically below -150°C (-238°F).

The primary function of a cryogenic valve is to regulate the flow of cryogenic fluids through a pipeline or system while maintaining the integrity of the equipment and ensuring safety. These valves are used to start, stop, or control the flow of cryogenic fluids like liquid oxygen, liquid nitrogen, LNG, and other gases that are kept in extremely low-temperature conditions.

The working principle of a cryogenic valve is similar to that of a regular valve, with some key design considerations to accommodate the extreme temperatures involved. Here's how a cryogenic valve typically works:

  • Material Selection: Cryogenic valves are constructed using materials that can withstand low temperatures without becoming brittle or losing their structural integrity. Stainless steels, aluminum alloys, and certain plastics are commonly used materials due to their low-temperature performance.
  • Sealing Mechanisms: Cryogenic valves are designed with advanced sealing mechanisms that can handle the contraction and expansion of materials as temperatures change. Traditional elastomeric seals might become too rigid or brittle at cryogenic temperatures, so specialized materials like PTFE (polytetrafluoroethylene) or metal-to-metal seals are used.
  • Thermal Insulation: Some cryogenic valves are equipped with thermal insulation to prevent excessive heat transfer from the surrounding environment, which could lead to operational issues. This insulation helps maintain the cryogenic fluid at the desired temperature and prevents icing or condensation on the valve's external surfaces.
