The Asco 8290A063 Solenoid Valve (8290A63) is a pressure-operated, angle-body piston valve that is normally closed. Its stainless steel body is suitable for corrosive, thermal, and hygienic processing conditions. With a 52 Cv and PTFE sealing flow rating, this valve is ideal for high-capacity clean-in-place (CIP) systems, chemical injection lines, and steam service in regulated processing environments.
