I just bought a home and my inspection found that the PRV has failed completely. I tested the water pressure at two outside hose bibs to make sure it just wasn't poorly adjusted (Both connect after the PRV I am sure, the main line comes straight from the street, through my concrete, to the PRV, and into the house) and it was 100 PSI regardless of how I adjusted the PRV nut.

Here's what my current main/PRV looks like: https://imgur.com/a/FF2Ll17

It looked like this valve would suit my needs https://www.homedepot.com/p/Wilkins-3-4-in-Pressure-Reducing-Valve-34-NR3XLDUR/310386815#overlay

The whole process doesn't seem to complex: Turn of water main, let remaining water out, brace pipe with one wrench and twist coupling with another, flush line briefly once PRV is off, make sure threads are clean, and install the new one.

I've seen some people wrap the threading in some teflon tape, is this good to do?

Thanks.
