I built my own sprinker system in CA. Use 1 inch valve and neck them down to 3/4 on the discharge side. After a number of heads neck the pipe down to 1/2 and add a few more. It keeps the pressure up. I was able to run about 20 heads on a run with 80 PSI at the valve.
On all main lines with pressure you need schedule 40, however on all sprinkler runs that isn't necesssary as the presure is discharged through the heads. When the valve is off there is no flow and no pressure. About 80 PSI is about the max you want to put on the mainlines. Anymore nad you need a pressure regulator, or you run the chance of blowing the mainlines apart. Also on every manifold you want a Turnoff Valve in case you need to repair that manifold. This way you do not have to shut the whole system down if you need to repair a valve or manifold.
