The pressure regulator on a top-mounted check valve is usually to the front or rear of the valve. Where the top-mounted check valve is a single feed, the side opposite the supply pipe would be plain. A top-mounted valve looks somewhat different from a side-mounted type. Below is a dual-feed top mounted valve, with both sides fed by lifting injectors:

Side-mounted check valves could be fed vertically, as Pete mentioned, or horizontally,as shown below:
