Valve with integrated pressure regulator

A regulating valve device for a fluid cylinder, comprising:

• a main body;
• a shut off valve having a ball tappet located within the main body that actuates the shut off valve;
• a residual pressure valve located within the main body and that is configured to supply fluid from the fluid cylinder to the shut off valve;
• a lever extending from the main body and having a cam surface that interacts with the ball tappet as the lever is rotated to translate the ball tappet linearly within the main body, wherein the lever is rotatable from a first valve closed position through a valve open position to a second valve closed position such that the valve open position of the lever is intermediate of the first valve closed position and the second valve closed position;
• a pressure or flow regulating valve downstream of the shut off valve and located higher along the main body than each of the shut off valve, the ball tappet, and the residual pressure valve;
• a handwheel operatively connected to the pressure or flow regulating valve to adjust a setting of the pressure or flow regulating valve;
• and
• a locking mechanism that prevents spontaneous adjustment of the setting of the pressure or flow regulating valve.

A regulating valve device for a fluid cylinder, comprising:

• a main body;
• a shut off valve having a ball tappet located within the main body that actuates the shut off valve;
• a residual pressure valve located within the main body and coaxial with the shut off valve;
• a lever extending from the main body and having a cam surface that interacts with the ball tappet as the lever is rotated to translate the ball tappet linearly within the main body, wherein the lever is downwardly rotatable from a first valve closed position through a valve open position to a second valve closed position such that the valve open position of the lever is intermediate of the first valve closed position and the second valve closed position;
• and
• a pressure or flow regulating valve downstream of the shut off valve and located higher along the main body than each of the shut off valve, the ball tappet, and the residual pressure valve;
• a handwheel operatively connected to the pressure or flow regulating valve to adjust a setting of the pressure or flow regulating valve, wherein the handwheel has an axis of operation that is offset from a longitudinal axis of the fluid cylinder by an acute angle, and wherein an internal surface of the handwheel includes a series of teeth;
• and
• an elastic finger having a tooth locatable in a tooth space along the series of teeth,
• wherein the shut off valve and the residual pressure valve are oriented transverse to the longitudinal axis of the fluid cylinder.
