Beduan Brass Electric Solenoid Valve, 1/2″ 24V NC

The Beduan 1/2″ 24V valve features a brass body with a copper solenoid coil, designed for reliable operation in water and air systems. Its 1/2″ NPT port size aligns with common plumbing and HVAC fittings, delivering robust performance for both home and light commercial projects. The device is NC (normally closed), ensuring flow is stopped when de-energized. The DC 24V coil provides responsive actuation, with emphasis on durability and consistent sealing through copper wiring and high-quality copper coil materials.
U.S. Solid 1/2″ Brass Electric Solenoid Valve 24VAC

This valve uses industrial-grade brass for corrosion resistance and welding compatibility, suitable for higher temperature applications. It employs a Viton seal, offering strong resistance to fuels, oils, and many chemicals. The valve opens or closes in less than a second when energized or de-energized, enabling rapid control for automated systems. Note that brass-based valves may not be suitable for drinking water; they excel in gas, fuel, and non-potable fluid applications with reliable cycle life in typical operating conditions.
U.S. Solid 1/2″ Brass Solenoid Valve – 24V DC NC

With a 0.1-10 bar range and a -30 to 150°C operating window, this 1/2″ solenoid valve is built for versatility. The brass body paired with Viton seals ensures durability and chemical resistance, making it suitable for water, air, and diesel lines in non-potable applications. The valve offers precise control with minimal flow fluctuations, ideal for systems requiring dependable shutoff and quick response times in 24V DC environments.
U.S. Solid 1/2″ Brass Solenoid Valve – 24V AC/DC

This solenoid valve offers a broad capability range with a 0.1-10 bar pressure rating and a -30 to 150°C temperature range. It uses sturdy brass and a Viton seal for durability under high temperatures and exposure to chemicals. The valve operates on AC 24V with tight tolerances to deliver consistent, non-fluctuating flow, suitable for automation projects and systems needing reliable remote actuation.
U.S. Solid 1/2″ Solenoid Valve with Viton Seal

This model emphasizes quick response with a sub-second open/close action and a robust Viton seal designed to resist high temperatures and aggressive chemicals. It is not intended for continuous duty in extended cycles; periodic rest is recommended to prevent core burnout. The valve is well-suited for controlled automation tasks where restart speed and seal resilience are priorities, including fuel, oil, and certain gas applications when non-potable fluids are involved.
Buying Guide
Key purchase considerations for 1/2″ 24V solenoid valves include valve material, seal type, and duty cycle. Brass bodies with Viton seals offer broad chemical resistance and strong durability for non-potable fluids, gases, and fuels, while stainless steel versions provide superior corrosion resistance in demanding environments. Consider the intended fluid (water, air, diesel, gasoline) and whether the valve is suitable for continuous operation or must be cycled intermittently.
Important specifications to compare include port size (1/2″ NPT), voltage (DC vs AC), and actuation speed. For quick shutoff or precise flow control, look for valves advertised with exact flow rate control and fast response times. Temperature and pressure ranges matter: ensure the valve can handle the operating range of your system, including surges and peak temperatures.
Installation and maintenance considerations: verify the electrical requirements (DC or AC) and whether a pilot or limit switch is included or needed. Check the valve’s life expectancy and cycling capability to estimate service intervals. If potable water is involved, select valves specifically rated for drinking water or consult the manufacturer for compatibility. Finally, consider whether a full port design is necessary to minimize pressure drop in your application.
