A method and system are provided for controlling a pressurized fluid such as nitrogen gas which tray be initially stored at a pressure as high as 20.000 psi. A valve assembly is utilized m the method and system and includes an electric proportioning device such as a pneumatic servovalve (14) and a pair of pneumatic fluidly-coupled valves (16 and 18) which are piloted by the servovalve (14) to regulate the pressure of the pressurized nitrogen gas. la the method and system, the servovalve (14) operates in a closed loop fashion by utilizing feedback from a feedback device such as a pressure transducer (40). A controller (46) in the closed loop is responsive m a pressure signal from the pressure transducer (40) and a preset reference signal to provide an error control signal to the servovalve (14).

Procédé et système permettant de réguler un fluide sous pression tel que l'azote gazeux qui peut initialement être stocké à une pression aussi élevée que 20 000 psi. Un ensemble soupape, utilisé selon ce procédé et dans ce système, comprend un dispositif de dosage électrique tel qu'une servosoupape pneumatique (14) ainsi qu'une paire de soupapes pneumatiques en communication fluidique (16 et 18) pilotées par la servosoupape (14) afin de réguler la pression de l'azote gazeux. Selon ce procédé et dans ce système, la servosoupape (14) fonctionne en circuit fermé en se basant sur les signaux de réaction provenant d'un dispositif de réaction tel qu'un capteur de pression (40). Un contrôleur (46) situé dans le circuit fermé réagit à un signal de pression provenant du capteur pression (40) ainsi qu'à un signal de référence préréglé pour fournir un signal de correction d'erreur à la servosoupape (14).
