I thought I saw a post by HotRod that showed 6 different connection options for zone valves. I'm interested in having a Pex A expansion connection. I'm trying to decide between the 676 series 1" valves with Twist top actuators, or the more conventional Z series.

I cannot find the info I'm looking for. Maybe they are not offered for the Z series. Can anyone help? Thanks!
