This 1/2 inch solenoid valve is designed for water and air applications and uses a normally closed NC configuration. It is available in AC 220V and DC 12V versions. When energized, the valve opens to allow flow; when deenerized it remains closed, providing a safe fail shutoff for irrigation and automation systems. Key benefits Failsafe normally closed operation: closes when not energized to prevent unintended flow and leaks. Precise control with energizetoopen action: ideal for automated irrigation and air line control. Standard 1/2 inch port size: compatible with common hoses, fittings, and irrigation components. Versatile media support: suitable for both water and air lines in various setups. Flexible voltage options: available in AC 220V and DC 12V to suit different control systems and controllers. Key attributes Function: Solenoid valve with N/C normally closed configuration; opens when energized. Port size: 1/2 inch. Media: Water and air. Voltage variants: AC 220V and DC 12V versions (matching the product's listed voltage options). Installation notes: The listing specifies 1/2 inch sizing and the solenoid actuation behavior; material details are not provided by the listing. Compatibility: Designed for garden irrigation tools and related automation projects; integrates with irrigation controllers, timers, and other control devices. Use cases Garden irrigation automation: Integrate with a timer or controller to precisely start and stop water flow to drip lines, sprinklers, or garden beds. Greenhouse irrigation system: Use in climatecontrolled irrigation circuits to deliver water on a scheduled basis, improving plant health and water efficiency. Small pneumatic or water line shutoff: Control compressed air lines or small water circuits in hobby or workshop setups where a reliable, electrically actuated shutoff is beneficial. Notes Verify voltage requirement (AC 220V or DC 12V) to match your control circuit before installation. Ensure compatible fittings and seals are used for a proper, leak connection with your 1/2 inch lines. Material specifics are not provided in the listing; consider user requirements for corrosion resistance and compatibility with your fluids when selecting components.
