Asco 低温电磁阀和液态CO2电磁阀
Features
• “LT” suffix valves are built to control cryogenic fluids,including liquid oxygen
(-297°F/-181°C), liquid argon(-303°F/-184°C), and liquid nitrogen (-320°F/-194°C).
• All suffix “LT” valves are degreased, cleaned, tested freeof moisture, and black light
tested for hydrocarbons.
• Liquid CO2 valves are suitable for remote mounting orfor direct mounting to the
refrigerated component by using four-hole bracket, provided.
