Normally open brass solenoid valve — 1/8' twoway valve, available in 12V / 24V / 110V / 220V / 380V coil versions (including 220V_NORMAL OPEN) Key benefits Normally open operation: valve remains open when the coil is unenergized and closes when energized, allowing failsafe flow in many systems and simplifying control logic. Compact 1/8' port size: fits tight spaces and smalldiameter piping commonly used in pneumatics, instrumentation, and small fluid lines. Robust brass construction: durable and corrosionresistant for reliable longterm use with water, air and compatible gases. Versatile coil options: available in multiple coil voltages (12V, 24V, 110V, 220V, 380V) so you can select the electrical rating that matches your control system. A specific 220V_NORMAL OPEN version is offered for 220V applications. What it does and how it solves problems Simple on/off control: as a twoway valve, it provides straightforward shutoff or permit flow between an inlet and outlet. Use it to isolate lines, automate supply lines, or integrate into pneumatic control loops. Failsafe default: because it is normally open, the valve allows flow when power is interrupted — beneficial for applications where maintaining flow during power loss is required. Broad compatibility: designed to handle water, compressed air and common noncorrosive gases, making it suitable for a wide range of industrial, commercial and hobbyist applications. Key attributes Functionality: Normally open (NO), twoway solenoid valve (on/off operation). Port size: 1/8 inch (sized for small piping and pneumatic tubing). Material: Brass body for durability and corrosion resistance. Coil voltages: Versions available in 12V, 24V, 110V, 220V and 380V. Specific model/version labeled 220V_NORMAL OPEN is available for 220V systems. Media compatibility: Water, air and compatible noncorrosive gases. Typical uses: pneumatic systems, fluid automation, gas control lines. Practical use cases Pneumatic control in small machinery: Automate air supply to actuators or control lines for tooling and fixtures where a compact, reliable on/off valve is required. Water or irrigation automation: Control small water lines, drip systems or automatic flushing circuits in residential or light commercial installations, with valve open by default until energized. Gas line isolation for equipment: Provide electrically controlled shutoff for lowpressure gas lines or pilot supplies in laboratory or light industrial applications where brass is suitable. Installation and selection notes Choose the coil voltage that matches your available power source (12V, 24V, 110V, 220V, 380V). The product is also available in a 220V_NORMAL OPEN variant for 220V systems. Confirm the 1/8' port size matches your piping or adapter needs before installation. Intended for water, air and compatible gases; verify chemical compatibility if using specialty media. Follow standard electrical and piping safety practices when wiring and mounting the valve. What you get A compact, normally open twoway solenoid valve with a brass body and 1/8' ports, available in multiple coil voltages including a 220V_NORMAL OPEN option, designed for reliable on/off control of water, air and compatible gases. If you require a specific coil voltage or the 220V_NORMAL OPEN model, please confirm the voltage option when ordering to ensure compatibility with your system.
