Water only flows through the valve when it receives an electrical signal (is energized). This design is ideal for irrigation systems because it automatically stops water flow during power outages, preventing unintended flooding or water waste.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which voltage should I choose — AC 220V, AC 24V, DC 24V, or DC 12V?\u003c\/h4\u003e\n\u003cp\u003eA: The right voltage depends on your irrigation controller or power supply. Most residential irrigation timers use AC 24V solenoid valves. DC 12V or DC 24V options are popular for solar-powered or battery-operated systems. AC 220V suits setups wired directly to mains power. Check your controller's output spec before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What pipe sizes is this solenoid valve compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This valve is available in three standard sizes: DN15 (1\/2\" BSP thread), DN20 (3\/4\" BSP thread), and DN25 (1\" BSP thread). Choose the size that matches your existing irrigation pipe diameter for a secure, leak-free connection.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this solenoid valve suitable for outdoor and agricultural use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The valve is constructed from durable nylon and plastic that resist corrosion and weathering, making it well suited for outdoor landscape irrigation, farm watering lines, and greenhouse systems. Its CE certification also confirms it meets quality and safety standards for reliable long-term use.\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 a solenoid valve?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A normally closed (NC) solenoid valve is closed by default when no electrical power is applied.
