City Water Intake Line: Why the Second Valve? Should I Scrap It?

I am replacing all the water lines in my 1978 Sovereign. I have two check valves, which I plan to replace with the Shurflo Pressure Reducing City Water Entry.

Question: the second smaller valve is attached to a drain line that feed out the bottom of my airstream, should I keep it as part of the new system?

Current System:

First Check Valve:

Second Check Valve:

Looks like a pressure relief valve. Would keep.

That is the pressure relief valve for the city water. It is set at 60 psi. If the pressure exceeds 60 psi, the excess water is routed thru the tube/hose that goes thru the floor.
