The Asco 8264G010 Solenoid Valve (8264G10) is a direct-acting, pilot-operated, normally closed valve developed for high-pressure liquid CO₂ control. With a Cv rating of 0.20 and 1/8″ NPT ports, this valve ensures precise shutoff in small-volume circuits up to 300 psi. It is frequently utilized in CO₂ feed systems, laboratory equipment, and low-temperature injection units.
