Each bed has 3 tees connected to 1/4" tubing with a one gallon per hour emitter on each end, so each bed has 6 emitters where the plants will go. Each stretch of 3 raised beds has a shut off valve, so have about 12 valves. I am using the shut off valves to control water pressure. So I have about 240 one gallon per hour emitters total. The water pressure is 75 gallons per hour, so I am thinking having three zones will be enough to water 75-80 plants one gallon per hour or two gallons per two hours. This whole thing is still work in progress, and I will be keeping you posted.
Any suggestions and feedback on my setup are highly appreciated.

Your water pressure is static pressure not gallons per hour, that is flow rate. That is determined by water pressure and pipe size.
The emitters are a set gallons per hour at a set pressure more than likely around 10 PSI or higher?
Your tanks at 5 feet and full will only have 2.15 PSI static pressure.
You cant control static pressure with a valve only flow which will only effect residual pressure while the system is running.
