Pressure Reducing Valves, Just turn down the mains stopcock?

Because turning down your stop cock does not reduce the pressure. It reduces the aperture the water passes through. Not the pressure at which it passes.
pressure reducing valves have sprung loaded mechanisms that adjust the throughput to the set pressure.
