3/4″ 12V DC Solenoid Valve
The 3/4″ 12V DC Solenoid Valve is a robust and efficient valve engineered for precise fluid control in automation, irrigation, HVAC, and DIY electronics. When powered by 12 V DC, the valve’s electromagnetic coil activates, lifting the plunger to allow smooth fluid passage. Once power is off, the valve closes automatically—ensuring leak-free operation.
Made from high-strength brass with a heat-resistant copper coil, this valve provides excellent durability, low power consumption, and fast switching capability. Its 3/4-inch NPT interface fits standard pipelines, making it a versatile solution for both industrial and Arduino-based smart systems.
