Abstract
Systems, apparatuses and methods for controlling valves through controlled power escalation towards the actuation threshold of the valve. A power signal is applied to a control input of a valve at a level less than a valve switch threshold at which the valve will be actuated. The power to the control input is then progressively increased. The valve is actuated when the power signal eventually reaches the valve switch threshold, thereby actuating the valve using a power signal commensurate with the actual valve switch threshold of the particular valve and its current operating conditions.
