When voltage is supplied (12V DC, 24V DC, or 220V AC), the valve opens to allow water flow. This is ideal for safety-critical systems where you want the water supply to stop automatically during a power outage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this solenoid valve suitable for hot water systems like solar water heaters?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This brass electric solenoid valve is rated for media temperatures of up to 55°C, making it well-suited for solar water heaters, standard water heaters, and other warm-water applications. Its all-brass construction provides excellent heat and corrosion resistance for long-term reliability.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which port size should I choose — G1\/2\" or G3\/4\"?\u003c\/h4\u003e\n\u003cp\u003eA: Choose the port size that matches your existing plumbing connections. G1\/2\" (½ inch BSP) is common in smaller residential appliances and drinking water systems, while G3\/4\" (¾ inch BSP) is typically used in larger plumbing lines, water heaters, and irrigation systems. Check your pipe fitting specifications before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I operate this valve manually if there is no power?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This solenoid valve includes a manual actuator, allowing you to open or close it by hand during power outages or for testing purposes — a very useful safety and maintenance feature.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does \\\"Normally Closed\\\" mean for this solenoid valve?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A normally closed (N\/C) solenoid valve remains in the closed position when no electrical power is applied.
