The Asco 8210G078LT Solenoid Valve (8210G78LT) is a pilot-operated, two-way normally closed valve, specifically designed for cryogenic fluid control. Based on the 8210G078 platform, this model is optimized for handling liquid oxygen, liquid argon, and liquid nitrogen. The valve is degreased, cleaned, moisture-free, and hydrocarbon-free, ideal for critical cryogenic applications.
For general-purpose valves, see Asco 8210G078.
