Tried 2 different valves of model lfx65bu and the lfn45bu and both pulsated and water hammered. My pipes sounded like a steam locomotive coming through the house . Exchanged for lf25aub-z3 and it solved all my problems .

Bought 4 of these valves after having a seal blow off at a rental home and then testing all properties. They worked fine at two of the rentals with a supply pressure between 100 and 120 psi. My house at the bottom of a hill and has supply pressure arount 150+psi. Put two different of these valves on and both sounded like a air horn in the basement. Do not trust the 300psi rating. Spent the extra $25 and get the double check valve, it is worth it to not have to redo the pipes twice. We also installed a different $40 watts valve and it failed after 3 days and was rated at 400psi.

Rated 4.0 out of 5.0 by j135 Watts were good
Installation was easy as it was replacing an existing PRV whose seat was leaking.
Increasing the output pressure above the factory set point created a chattering in the house piping. My input pressure is 140# which may be part of the problem causing the chattering but the old valve never chattered from day 1.
Had to settle for 50# output to keep valve from chattering. Aside from this problem there is little pressure drop thru the valve and holds pressure when there is no flow.

Rated 1.0 out of 5.0 by Devon NOISY AND CAUSED WATER HAMMER
First time using this model of P.R.V. and it will be my last time! Installation is standard as with all female N.P.T. adapter valves. Factory setting was 50 PSI, adequate enough. The issue was once the water is turned back on. There was water hammer galore. First thought it was an old fill valve that needed to be replaced in an upstairs toilet. After that was done, the noise stopped.... only to return when another toilet was flushed and when the washing machine was used. After adjusting the PSI both up and down (thought the internal spring could be sticking) had to keep it set at 80 PSI. The unit should function normally within the manufacturer's recommended pressure range. It clearly did not.

Rated 2.0 out of 5.0 by pwrgreg007 Not for every house
Our 3 bedroom, 2 bathroom house with CPVC piping needed a new pressure regulator. After installation however, this unit, when using any one water draw like a toilet, shower, or washing machine, had a resonance/pulsing issue. With pressure gauge attached it would oscillate between 30-50 psi at about 3 pulses per second (whoosh, whoosh, whoosh) and the pipes were shaking around. I talked to HD support who said it could be a restriction in the line to the house, which I tested and ruled out. He said to try another unit, which I did, with the same result. I got the Watts 3/4 LF25AUB-Z3 unit and the problem was fixed.
I gave the unit two stars, even though it didn't work in my home, because it may work fine in many installations. If you get a pulsing issue, just get the more expensive unit. I can only choose yes/no on recommendation, so I chose no. Others have had good results, apparently.

Rated 5.0 out of 5.0 by Rick Works great!
Had lots of banging and hissing in the main inlet prior to installing this. Now there is none. My installation was a bit of a pain but that is the fault of the person who installed the original one. Glad I didn't get one of the plastic ones because I dropped this on the kitchen floor before installation. Pressure is just over 50psi with nothing running, just under 50psi with a faucet and toilet running.

Fairly Easy to install and fits nicely. No more Whine like the worn out part.

Rated 4.0 out of 5.0 by CCcc works fine
The other guy must not have gotten all of the air bled out of his system. Mine does not hammer. I did have to take off the old flange nut and replace with the one that came with the unit. Mine (about 10 yr-old Wilkins unit) had different threads.
