{"title":"Solenoid Valve-DN20","handle":"solenoid-valve-dn20","url":"/products/solenoid-valve-dn20","description":"A 12V DC motorised solenoid valve with a DN20 (20 mm) bore, designed for controlling water flow in automated projects. The valve integrates a DC motor with a metal reduction gearbox, providing high torque and low noise operation. It withstands up to 1.0 MPa static pressure.\n\nThe valve has three control wires: connect the blue wire to positive to open, the red wire to positive to close, and the yellow wire to ground. If power is removed, the valve holds its current position and can also be operated manually.\n\nKey Features\n\n\nMotorised Control – DC motor with metal reduction gearbox for reliable open/close operation\n\nThree-Wire Interface – Blue (open), red (close), yellow (ground)\n\nHolds Position – Maintains current state when powered off, with manual override\n\nSealed Motor – Waterproof design for reliable operation\n\nAnti-EMI – Electromagnetic interference shielding\n\n\nSpecifications\n\n\nBore Size – DN20 (20 mm / 0.79\")\n\nRated Voltage – 12V DC\n\nRated Current – 100 mA\n\nRated Power – 2W max\n\nValve Pressure – 1.0 MPa\n\nTorque – 30–60 kg·cm\n\nInsulation Resistance – >20 MΩ\n\nOperating Temperature – –10°C to +50°C\n\n\nWiring\n\n\nBlue wire – Connect to +12V to open valve\n\nRed wire – Connect to +12V to close valve\n\nYellow wire – Ground (shared)\n\n\nIdeal For\n\nAutomated irrigation and agriculture\nSmart home water control\nAquaculture and fisheries\nArduino and Raspberry Pi water management projects\n\n\n\nTip: Use a relay module to switch the 12V valve from a microcontroller, allowing timed or sensor-triggered water flow control.\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4719,"title":"Default Title","sku":"DF-FIT0617","price":45.48,"on_sale":false,"in_stock":true,"available_quantity":171,"option1":"Default Title"}]}
