Prince Adjustable Relief Valve - 1/2in., Model# RD-1850-H
Part is good, description from Northern needs work
The part is good, and works fine.
The description from NorthernTool is incomplete. The valve has a total of 3 ports, two are on opposite sides and act as in/out ports. The third port is to be directed to the tank, and is labeled as such.
The pictures and description from Northern only lists the port size, it doesn't say the number of them or their function. When you're designing a system, that information is critical. In my case, I ended up ordering more fittings than necessary for my system.

Prince Pressure relief valve
Very easy to install and adjust. The valve works great, but can be a bit loud when bypassing. I buy 30 to 40 a month and have never had one fail.

I have used over 100 of these valves due to a large contract I have. I have to say that when they do work properly they are great. The overall desing is pretty simple to use, there are not a lot of ways to mess it up or adjust it wrong. The main issue I have with these valves is they are about 40% reliable and that makes them only average in my book. Had they been more reliable I would have given them 5 stars because they work very well when they do work.
