Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening project. There are two 1/2" / 12.7mm (Nominal non-taped National Pipe) outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can push through. The solenoid is not polarity sensitive to polarity so there is no risk in connecting it backwards. The valve has a gasket arrangement inside, so there is a minimum pressure requirement of 0.02 Mpa (3 PSI) and it should only flow in one direction (note that there is no integrated one-way check valve).
Adafruit tried this solenoid at various DC voltages and found it could actuate down at 6VDC (although it was a little slower to open). Here is the current draw table for various voltages. We suggest a TIP120 or N-Channel power FET with a 1N4001 kickback diode to drive this from a microcontroller pin. For a power supply, the Altronics 12V - 2A will do the job.
If you want a beefier water valve, We also carry a brass version which does not have a minimum pressure requirement and can be used with liquid flow in either direction.
Voltage | Current |
6V | 160 mA |
7V | 190 mA |
8V | 220 mA |
9V | 240 mA |
10V | 270 mA |
11V | 300 mA |
12V | 320 mA |
These solenoids are not rated for food safety or use with anything but water.
