I would like to alternate water flow between 2 pipes based on a timed event, so id have 1 input and 2 outputs. Water would flow primarily through 1 of the output pipes, but every now and again is like to switch to the other pipe. Does anyone have any experience of doing this? I was thinking some kind of solenoid, but can't find the right one.
Thanks in advance,
Martin.
Look for solenoid valves. Most are AC operated and to be controlled by Arduino, need Arduino-compatible relays.
My problem is finding the correct solenoid valve. The only ones I have seen are either 2 way (on/off) or the 3 way ones seem to have one of the ports as an exhaust port, so wouldn't work how I want them to.
Use two of those with a T pipe junction. Done.
3 way, 2 position valve, 3 ports (A,B,C). Position1(solenoid OFF), fluid flows in A, out B. Position 2 (solenoid ON), fluid flows in A, out C.
3 way sol valve
3 way motorized valve
