A pneumatic pressure regulator comprised of at least an obturator actuated by at least an elastic membrane comprised of at least an inlet orifice which permits the entry of a fluid under pressure and comprises at least an outlet orifice which permits the exit of a fluid under regulated pressure, characterized by a programmable means (6) which creates a force F on the obturator (2), this force F being defined at the end of a test by varying the value of at least a parameter P of the functioning of the regulator in such a manner that the outer pressure PS=f(P) of the regulator is exactly equal to the value of the predefined pressure PD=f(P) for each value of the parameter P of the operation of the regulator.

A pneumatic pressure regulator comprising: an inlet orifice; an inlet chamber in communication with said inlet orifice; an outlet orifice which permits exit of fluid under a regulated pressure, PS; a regulation chamber in communication with said outlet orifice; a reference chamber defined by an elastic membrane having a sensing area SE which forms a boundary between said regulation chamber and said reference chamber; an obturator operatively arranged to control flow and regulate pressure of gas flowing from said inlet chamber to said regulation chamber via a passageway therethrough, said obturator actuated by said elastic membrane; a programmable controller; and, means responsive to said programmable controller for applying a force F to said obturator, said force F being determined as a result of a test of said regulator, said force varying as a function of a parameter P such that said outlet pressure PS=f(P) is exactly equal to a predefined pressure PD=f(P) for each and every value of parameter P.
