The Asco 8290A064 Solenoid Valve (8290A64) is a rugged angle-body piston valve built to manage corrosive fluids and steam in harsh industrial settings. Its stainless steel body resists chemical attack, while PTFE sealing ensures long-term reliability in high-purity and aggressive service. This configuration supports critical operations in food-grade systems, caustic washdowns, and chemical batch lines.
