The Asco 8263G059 Solenoid Valve (8263G59) is a compact, direct-acting two-way valve engineered for high-temperature steam applications. It operates without pressure differential, making it ideal for low-pressure shutoff and control. Designed for durability in thermal systems, it performs reliably in autoclaves, sterilizers, food service equipment, and other steam-based applications.
