Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening project. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can push through. This is a gravity fed solenoid valve (water flow direct from overhead tank) so it requires zero pressure to open and close the valve. Do not use it with a pump otherwise it will not function as required. Also, liquid can only flow one direction. Flow direction is indicated on the bottom of the valve with an arrow. If you require a valve to be used with a pump check the minimum pressure valve.
We tried this solenoid at various DC voltages and found we could actuate it 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, our 9V 1A or 12V 1A power adapters 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.
