The Asco 8290A501 Solenoid Valve is a normally closed, angle-body piston valve for handling high-volume thermal discharge and process media. With a 316L stainless steel body and 125 mm actuator, the valve efficiently handles steam, slurries, and solvents while minimizing hammering through its under-disc path.
