Installing new PRV valve

[Greg814]

So I'm installing a new prv valve. My old one had failed and I had no flow. What would be the best way to attach the prv to pvc since it has metal threads. I've read where its best to try and avoid plastic to metal threads. I'm just a diy'er. Also where would be the best place to install a ball valve since no one ever installed one. Pvc or brass ball valve? I bought a Zurn 70XLDU PRV.

I would put an access box to your new PRV as then you can maintain and change the pressure easier.
