The Asco 8290A030 Solenoid Valve (8290A030) is a pressure-operated, direct-acting angle-body piston valve with a normally open configuration and entry under the disc. Designed for aggressive media handling, the valve delivers fast, high-capacity discharge in general and high-temperature service lines. It is commonly installed in CIP skids, hot water systems, and food and beverage processing loops.
