Need help with gravity fed remote watering

I'm having issues getting the timed battery operated valve to work with the low pressure. The box says it requires 10-100 psi to operate, which I'm guessing I have just under 10 PSI with about a 6' elevation change between my water reservoir and the lower ground which I am watering.

Any ideas?

Here's an overhead view for reference. I'm running irrigation lines on a battery operated timer, to the 40X40 grow area, which is about 6' lower in elevation that my water reservoir.

Oops! forgot to mention there is no electricity or solar set up and I would like to keep as low tech as possible.

I guess the first question would be; Do they make battery operated timers that run on little to no water pressure?

video of low pressure, battery operated water valve  This might be of help.

Orbit makes a battery operated timer valve that needs lower pressure than 80 psi to operate, there is no mention of the lowest water pressure it will work at, but I imagine it would work for your situation.

The other choice would be to elevate the tank so the head pressure would be 10 psi. That means you need at least 10 feet of drop to the valve from the tank with a 1 inch line.

Hey man, your name is familiar...are you on the backyard aquaponics forum too?

Anyhow I jumped the gun making this thread without doing enough digging. I ended up finding a ball valve timer that will run on 0 PSI. The key search word was " no pressure rain barrel timer" The cheapest model I found was the toro and lowest price on that model was direct from the dealer in case anyone else is interested:

We've hit a dry spell and I am having to drive 2 hours round trip just to water! as a result I paid for the 2 day shipping lol. Wish me luck. HOpefully this solves it.

At my last place I had the same problem and went with a solar charging zero pressure timer.  I can't find the one I used but this one looks to be pretty similar Mr Drip
