The Asco 8290A024 Solenoid Valve (8290A24) is an angle-body, pressure-operated, normally closed valve engineered for high-flow shutoff of hot water, steam, and inert process fluids. It’s 68 Cv rating and proportional control capability supports rapid throughput with minimal pressure loss. Typical applications include tank cleaning systems, large CIP skids, and industrial utility manifolds.
