This invention provides a fluid control system for regulating flow fluid under extreme conditions and includes a reciprocal a reciprocal 1 control module and rotary control module. This system provides energy transmission devices to regulate a flow fluid rate and flow fluid pressure in different manners with minimum pressure loss consequences. This system also has a dynamic stem seal assembly which comprises an inclusive stem packing, bore packing, and secondary seal for compensating any offset and is provided with a leakage between 10-500 ppm and a controllable loading device and a dynamic seat seal assembly which comprises a body seal and valve member seal for compensating any offset and is provided with zero leakage and novel mapped solutions with a metal-to-metal seal ultimate goal-pointed seal ring. This system provides a number of novel mechanical joint devices.
