Abstract
A valve arrangement for a pressurized fluid source includes a regulating valve poppet configured to translate along a longitudinal axis of a valve housing, and a linear stepper motor configured to control a position of the regulating valve poppet. The linear stepper motor is controlled by a closed loop control system based upon temperature and pressure feedback signals to actively control the position and stroke rate of the regulating valve poppet.
