The present invention describes, generally, a method and system for controlling the dynamics of an actuatable load functioning or operable within a servo or servo-type system, wherein the dynamics of the load are controlled by way of a unique pressure control valve configured to provide intrinsic pressure regulation. The pressure control valve, which may be referred to as a dynamic pressure regulator because of its capabilities, utilizes dual spools that are physically independent of one another and freely supported in the valve body to regulate the pressures acting within the overall system between the control or pilot pressure and the load or load pressure. The dual spools of the pressure control valve, although physically independent of one another, function in cooperation with one another in an attempt to maintain a state of equilibrium in the system, namely to keep pressure acting on or within the actuator (the load pressure), or the feedback force corresponding to the load pressure, the same as the control or pilot pressure. Moreover, pressure regulation and control is intrinsic to the pressure control valve because of the configuration and function of the dual spools and the mechanical feedback system acting on the spools, thus eliminating the need for electronically or mechanically user controlled systems.
