The Asco 8222G005 Solenoid Valve (8222G5) is a pilot-operated, normally closed steam valve for high-pressure thermal systems. It handles up to 200 psi at 388°F and opens with as little as five psi inlet pressure. A 3/4″ NPT inlet and a 4.6 Cv flow rating make it suitable for delivering controlled steam to sealed, high-load applications.
