I have a lot of experience with Rain Bird valves. I generally use the Jar Tops or DV-100 series. I have had conversations with the Rain Bird rep about the Jar Tops and he said Rain Birds intent was for them to be the cheap, entry level valves but in failure testing, they actually outperformed the DV series. Better valves for a little less money is a good combo. The only thing that prevents me from exclusively using Jar Tops on residential jobs is the flow rate. DV's have a little more flow than Jar Tops so you have to be aware of your flow demand and look at the flow charts for the valves you are considering. Flow charts are available at Rain Birds web site.

The 100 PGA valve is a sound choice. It is durable, proven and has some extra benefits that other valves do not. My only concern is the amount of water you will need to use on your drip zone to allow the valve to function correctly (more than likely all you will need is some filtration before the valve). I have provided a link for you to research the valve. Best of luck!

Valve Selection Advise

Thanks in advance to all who respond.

I have went through the Rainbird design process, and then used the Irrigation Tuturials website extensively to double check, and slightly modify the design. Of course Rainbird suggests spray's such as the SurePop series, etc. which I have decided to upgrade, along with other components, to 1800 SAM PRS series, based on some limited conversations with some pro installers.

Along those same lines, Rainbird suggests JarTop series valves, which I get the impression are at the lower end of the quality scale? I am currently looking at the "100-PGA - RainBird 1 inch Threaded Inlet/Outlet PGA Series Valve" as a possible upgrade.

I've got a total of 9 zones (8 standard, plus 1 drip) and I'm looking for a quality (sub $50, preferably sub $30), easy maintenance / serviceable valve.
