Brass 3/4" 2-way Normally Open Electric Ball Valve — 12V DC, 2-wire (inline) What it is and how it helps Compact inline ball valve for reliable on/off control of water lines in residential or light commercial systems. Uses a 2-wire 12V DC coil for simple wiring and fast actuation, making integration with low-voltage controllers straightforward. Normally open configuration means the valve allows flow by default; energizing the coil closes the valve for fail-safe behavior in many setups. Key specifications Material: brass (corrosion-resistant, durable) Size: 3/4 inch Configuration: 2-way inline connection (inlet/outlet) Coil voltage: 12V DC Wiring: 2-wire Operation: normally open (flow present when de-energized) Why customers need it — key benefits Simple integration: 2-wire 12V DC coil works with common low-voltage controllers and smart relays. Safety by default: normally open design allows flow if power is lost, useful for applications that require default supply. Durable construction: brass body resists corrosion and supports long service life in water systems. Space-saving: compact inline form factor fits under sinks, inside manifolds, and in tight equipment cabinets. Low power and fast response: efficient coil and quick actuation reduce energy use and improve system responsiveness. Easy installation: standard 3/4" inline connections and straightforward wiring minimize setup time. Typical applications Under-sink appliance control: automate water to dishwashers, ice makers, or filtration systems with a smart controller. Irrigation and greenhouse manifolds: schedule or automate watering zones with reliable, low-voltage valves. Smart-home water management: control small boilers, humidifiers, or point-of-use devices where energizing the coil closes the valve. Installation and operation notes Valve is normally open; applying 12V DC to the coil closes the valve. Verify your control logic matches this behavior. Requires a 12V DC supply capable of driving the valve coil. Use appropriate wiring and protection for low-voltage circuits. Inline connection (3/4") matches standard plumbing fittings; confirm thread/type compatibility before installing. This valve provides a reliable, compact solution for low-voltage automated water control while maintaining clear, safe default behavior and durable brass construction.
