ASCO 8210B20 2-Way Solenoid Valve 1/4 NPT 120 VAC

The ASCO 8210B20 is a 1/4" NPT, 2-way, normally closed solenoid valve with a 120 VAC coil, designed to quickly switch airflow in pneumatic systems and inert-gas lines. The red-hat variant features a brass body with NBR seals for durability in industrial environments and standard 1/4" NPT ports, making it a compact choice for tight installations. With a flow coefficient (Cv) around 0.88 and an operating pressure range of roughly 5–125 psi, it provides reliable control between inlet and outlet when energized, suitable for automation equipment, pneumatic actuators, and vacuum control applications. This 2/2 valve is commonly used to regulate air pressure or vacuum in machinery where a compact, electrically operated valve is required, and it is wired for standard 120 VAC, 60 Hz power in industrial settings.
