Applicability:
Low temperature ball valves are mainly used in the chemical equipment of LNG gas to handle low temperature liquid medium like ethylene, liquid oxygen, liquid hydrogen and so on. These types of inflammable and explosive medium can be volumetrically expanded by several hundred times when being gasified under room temperature, and are difficult to manufacture due to their highly penetrative and leaky properties.
Structural Properties:
1. The extension of the stem and expansion of parts can avoid the expansion and contraction of the packing box, making the parts separate away from low temperature to maintain good seal of packing boxes, and can be used without limitation to the number of open and close operations.
2. The valve seat is made of PTFE or other materials with good low temperature resistance, ensuring reliable sealing performance.
3. The ball valve is designed to prevent static electricity and fire, ensuring safety during operation.
4. Low temperature ball valves must function dependably and maintain their properties under the conditions of temperature changes.
