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" (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 valve has a gasket arrangement inside, so there is a minimum pressure requirement of 0.02 Mpa (3 PSI). Also, liquid can only flow one direction.

Adafruit tried this solenoid at various DC voltages and found Adafruit 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, Adafruit's 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 and can be used with liquid flow in either direction.

    Intended purpose .. cat shower ( for backyard pussies ) .. useing 12v DC PIR motion detector, activating the solenoid before an impulse sprinkler. Project not finished as I am waiting for the arrival of a quality PIR.
    If interested will send pics when I'm satisfied with the result. Regards Robbie (Posted on 26/07/2017)

    The valve works fine, however if you are running low pressures through it (like a gravity feed or a weak pump) you may be disappointed. The minimum operating pressure means that it is more suited for medium pressures. (Posted on 17/11/2014)
