01 — About

What it does

The 12V Solenoid Valve is a compact, robust 2-way normally closed (NC) electric solenoid valve designed for controlling the flow of water, air, gas, and other compatible liquids in embedded systems, automation projects, and IoT applications. Featuring a 1/4″ NPT female port, brass body construction, and a 12V DC coil, it is ideal for use with Arduino, Raspberry Pi, ESP32, and other microcontroller platforms when paired with a relay or MOSFET driver circuit. The valve opens when energized and closes automatically when de-energized, making it perfect for automated watering systems, pneumatic controls, and fluid dispensing projects.

Key features

  • 12V DC operating voltage
  • 2-way normally closed (NC) operation
  • 1/4″ NPT female port for standard fittings
  • Brass body for durability and corrosion resistance
  • Direct-acting solenoid mechanism
  • Fast response time under 20ms
  • Compatible with Arduino, Raspberry Pi, and ESP32
  • Low power consumption design
  • Compact form factor for embedded installations
  • Long service life of up to 200,000 cycles

Good to know

  • Never connect the solenoid directly to Arduino/Raspberry Pi GPIO pins — the 12V coil will damage the microcontroller. Use a relay module, MOSFET, or motor driver board.
  • Ensure a 12V DC power supply with sufficient current (minimum 1A recommended per valve).
  • Install a flyback diode (1N4007) across the coil terminals to protect your driver circuit from voltage spikes.
  • Verify the working pressure range matches your system requirements before installation.
  • Do not use with corrosive or high-temperature fluids beyond the seal rating.
  • Mount the valve with the coil facing upward for optimal performance and longevity.
  • Ensure proper thread sealing (Teflon tape) when connecting NPT fittings to prevent leaks.
