The Asco 8263H303 Solenoid Valve is a normally closed, direct-acting valve used for steam and hot water control in high-temperature, low-pressure systems. It provides reliable shutoff performance at temperatures up to 307°F for steam and 210°F for hot water. Typical applications include compact autoclaves, sterilization panels, and thermal loop skids.
