The Asco 8290A394 Solenoid Valve is a pressure-operated, angle-body piston valve with a stainless steel body, 50 mm operator, and normally closed configuration. Designed for steam, water, air, and light slurry service, it delivers reliable shutoff under high temperatures and frequent cycling. It is ideal for corrosive or sanitary systems requiring robust actuation and long service life.
