The Asco 8290A386 Solenoid Valve is built for thermal process control involving fast-acting, high-temperature media. Its normally closed configuration and pressure-operated design make it suitable for isolating steam, solvents, or CIP fluids in skid systems, spray stations, and service lines that require reliable shutoff under thermal and chemical stress.
