The Asco 8290A393 Solenoid Valve (8290A393) is a pressure-operated, angle-body piston valve with a stainless steel body and normally closed configuration. Designed for aggressive fluids and elevated temperatures, it performs reliably in chemical wash zones, thermal loops, and hygienic CIP systems. It is suitable for installations requiring high corrosion resistance and compact actuation response.
