Overview
The ASCO 8030G10 Red Hat II solenoid valve is a two-way general-purpose control valve engineered for direct-acting low pressure and vacuum service. The 3/8″ brass body with 120-volt AC coil design makes this valve suitable for a broad range of fluid control applications, including pool systems, water treatment, compressed air circuits, and light-duty pneumatic equipment.
