Check out the Bermad FP 436. It is a “pressure sustaining valve.” I’ve seen water purveyors require these so that you don’t draw the suction line below 20 psi. It is installed in the pump discharge. It also acts as your pump discharge check valve.

Basically, this throttles the flow from the pump and keeps the municipal system pressure from going negative.
