Works well
This valve was a direct replacement of my fault one, easy to install with basic knowledge, shipped with correct parts. 4 months in and no more issues

No Union Collar
Pretty hard to install this PRV without a union collar which is shown in all three pics.

Missing O- Rings But right part itself fit perfect
Missing the O-Rings had to use old ones 🤞 but other than that it's a exact fit and delivered early.

Perfect drop-in replacement for a N35B 3/4" pressure reducer
Arrived 2 days early. It was easy to install once I managed to remove the old unit. I used teflon tape on the threaded pipe output and a little silicone grease on the input o-ring. No leaks. Preset pressure was 60 psi. Works perfectly and less expensive than local options.
