OK to Use 3/4" Brass Valve with PVC Pipe?

First, thanks to everyone who has given me much-needed advice about my PVC sprinkler system project. This forum is a Godsend for us non-professional plumbers. I have what I hope is a final question:

To recap, I've tapped into my copper main water supply line with a brass Tee and run 10 feet of 3/4" Schedule 40 PVC to my sprinkler controls. My original plan was to put a PVC ball shutoff valve just before the controls. But contributors to this forum have warned that those often get stuck or the handles break. I don't want to deal with that several years down the road.

Plan B is to use a new BRASS gate valve (or go the extra cost for a ball valve) with PVC male adapters threaded into the input and output. The galvanized steel pipe which I'm replacing had one of those valves and it's still going strong after 30 years. The steel pipe is rusted to hell but the valve works fine. I'm just wondering if there's any problem I'm not aware of with using a brass valve in a PVC line.

This is basically duplicate of http://www.doityourself.com/forum/pl...d-3-4-pvc.html. Yeah, we read 'em all. The brass ball valve will work fine with the pvc male adapters, or female adapters, whichever type valve you plan on using.
