The 12V Solenoid Valve G1/2 DN15 BSPP Pressure Type is a normally closed electric valve designed for automatic control of water, air, oil, and other non-corrosive fluids. When 12V DC power is applied, the valve opens instantly, allowing fluid to flow through. When power is removed, the valve automatically closes, making it ideal for automated irrigation, water dispensers, fuel systems, pneumatic controls, and industrial automation.
