The Asco 8263H306 Solenoid Valve is a direct-acting, normally closed valve used for compact steam and hot water shutoff applications. With a Cv of 0.85, it delivers steady mid-range flow while operating up to 316°F steam and 95 psi hot water. This model is commonly specified for autoclaves, rinse skids, and heat-driven process loops.
