A two-step, self-regulating valve (16) controls gas flow from a gas cylinder (12) in a high pressure system. The valve (16) includes a valve body (24), a piston (26), a plug (28), a valve actuator (34), and a piston actuator (32). The piston (26) is movable within the valve body (24) along an axis between a first and a second position. The plug (28) is movable within the valve body (24) along the axis between a valve closed po-sition, a partially open position, and a fully open position. The valve actuator (34) allows the plug (28) to move from the valve closed position to the partially open position. The piston actua-tor (32) causes the piston (26) to move from the first position to the second position when a gas pressure in the gas cylinder (12) is less than a setpoint. When the piston (26) moves to the second position, the piston (26) allows the plug (28) to move from the partially open position to the fully open position.
Valve (16) autorégulée en deux phases régulant l'écoulement de gaz à partir d'une bouteille de gaz (12) dans un système haute pression. La valve (16) contient un corps de valve (24), un piston (26), un bouchon (28), un actionneur de valve (34), et un actionneur de piston (32). Le piston (26) est mobile dans le corps de valve (24) le long d'un axe entre une première position et une seconde position. Le bouchon (28) est mobile dans le corps de valve (24) le long de l'axe entre une position de valve fermée, une position partiellement ouverte, et une position grande ouverte. L'actionneur de valve (34) permet au bouchon (28) de passer de la position de valve fermée à la position partiellement ouverte. L'actionneur de piston (32) conduit le piston (26) à passer de la première position à la seconde position lorsqu'une pression de gaz dans la bouteille de gaz (12) est inférieure à un point de consigne. Lorsque le piston (26) passe à la seconde position, le piston (26) permet au bouchon (28) de passer de la position partiellement ouverte à la position grande ouverte.
