12V 24V G1/2" Plastic Solenoid Water Valve NC/NO Irrigation
12V 24V G1/2" Plastic Solenoid Water Valve NC/NO Irrigation
Details
12V/24V Plastic Solenoid Water Valve — G1/2" | NC & NO | Washing Machine, Garden & Irrigation
Take full control of your water flow with this versatile G1/2" Plastic Electrical Solenoid Water Valve. Available in both Normally Closed (NC) and Normally Open (NO) configurations, this pilot-operated solenoid valve is engineered for reliable, automated water management across a wide range of applications — from washing machines and water dispensers to garden spray systems and drip irrigation setups.
With a robust service life of 500,000 cycles and a wide working temperature range of 0–90°C, this solenoid valve is built to last in demanding everyday conditions. The adjustable coil angle (90°, 180°, 360°, 720°) makes installation flexible and convenient in tight spaces.
Made in Mainland China.

Frequently Asked Questions
Q: What is the difference between Normally Closed (NC) and Normally Open (NO) solenoid valves?
A: A Normally Closed (NC) solenoid valve is closed when no power is applied — water flows only when the coil is energized (power on = water on). A Normally Open (NO) valve is open with no power and closes when energized (power on = water off). Choose NC for most standard irrigation and appliance applications, and NO where you need water to flow during power outages.
Q: Is this solenoid valve compatible with standard garden hose fittings?
A: This valve features a G1/2" (20mm) thread, which is a widely used standard in plumbing and garden irrigation. It is compatible with most G1/2" threaded fittings, connectors, and hose adapters commonly used for washing machines, water dispensers, and garden spray systems.
Q: Can this valve be used with DC 12V from a battery or Arduino/microcontroller?
A: Yes! The DC 12V variant draws only 0.55A and works well with battery packs, relay modules, and microcontroller-driven systems such as Arduino or Raspberry Pi setups — making it ideal for smart home automation, automated irrigation timers, and DIY water control projects.
Q: What liquids is this solenoid valve suitable for?
A: This valve is designed for use with purified water and drinking water. It is not suitable for acidic, alkaline, thick, or viscous liquids, as these can damage the internal components and void the valve's performance rating.
