The downstream pressure senses the lower side of the valve membrane through the internal pressure.
When the downstream pressure reaches or exceeds the set pressure,the valve plug hits the valve core and blocks the fluid passing through the voltage regulator.When the downstream flow demand increases,the downstream pressure drops slightly,making the spring elongate,the stem moves down,the plug leaves the core,and the fluid passes through the pressure reducing valve.
