It appears you're already getting good help on a pump, so I'll just suggest another odd possibilty, which is a different kind of valve. A regular irrigation valve usually requires at least 20psi (137kpa) to function. You could use a solenoid valve, which requires no pressure to switch. You'd still have really low pressure, but if you're ok with that, it would work. Here's an example chosen at random from the amazon.com listing for "solenoid valve" https://www.amazon.com/HFS-Electric-Solenoid-Valve-Water/dp/B018WRJYOU
These valves just close and open electrically, so they don't care whether there's any flow or pressure at all, or even what's flowing through the pipe (air, water, etc). A diy home automation system could readily open and close these valves using some relays.
