The Asco 8220G408 Solenoid Valve is built for systems that need strong, fast flow with no inlet pressure buildup. Its high-capacity design handles both steam and hot water, and supports full AC and DC operation. Ideal for CIP rinsing, industrial washers, and heat-driven spray systems where fast response and low-pressure startup are critical.
