When the coil is energized with the correct voltage (DC 12V, 24V, or AC 220V), the valve opens and allows water to flow. When power is cut, the valve automatically closes again. This design is ideal for energy-saving and fail-safe water control applications.\u003c\/p\u003e\n\u003ch4\u003eQ: What pipe thread sizes are compatible with this solenoid valve?\u003c\/h4\u003e\n\u003cp\u003eA: This solenoid valve is available in 1\/2\" and 3\/4\" male thread sizes. Please refer to the thread size reference guide above to confirm the correct outer diameter for your plumbing setup before ordering. Slight measurement tolerances (0.2–0.5mm) are normal for standard threaded fittings.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this solenoid valve suitable for hot water use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, this valve supports working temperatures up to 90°C, making it suitable for hot water applications as well as cold tap water and pure water. It is not rated for steam or highly pressurized systems beyond 0.8 MPA.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this valve with an Arduino or Raspberry Pi automation project?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
