An intermediate chamber extends between a probe chamber and proximal chamber of the valve body along a main axis. A control port extends radially of the main axis. A valve pin is received by the intermediate chamber and movable between closed and open positions. A control plug is received by the control port and actuatable between on and off positions. Fluid communication between the proximal and probe chambers through the valve body is enabled when the valve pin is in the open position and the control plug is in the on position. Contrastingly, such fluid communication is prevented if either the valve pin is in the closed position or the control plug is in the off position. The control plug is preferably located in radial alignment along the main axis with at least a portion of the valve pin. ## Claims ### Claim 1 A cylinder valve assembly with actuatable on-off-control, the assembly comprising: a valve body including (a) a probe chamber and a proximal chamber disposed along a main axis, (b) an intermediate chamber extending along the main axis between the probe chamber and the proximal chamber, and (c) a control port extending radially of the main axis;

and wherein the control plug is located in radial alignment with at least a portion of the valve pin when the valve pin is in the closed position and the open position, the radial alignment being defined perpendicularly to the main axis. ### Claim 2 (depends on 1) A cylinder valve assembly as defined in claim 1 wherein the valve body further includes (a) a bypass channel in fluid communication between the intermediate chamber and the control port; and (b) a control channel configured to, irrespective of whether the valve pin is in the closed position or open position, be in fluid communication between the control port and the probe chamber when the control plug is in the on position. ### Claim 3 (depends on 2) A cylinder valve assembly as defined in claim 2 wherein (a) the control channel includes a control valve seat; and (b) the control plug includes a control valve axial seal configured to (i) be in sealing engagement with the control valve seat when the control plug is in the off position, thereby sealing the control channel from fluid communication with the control port; and (ii) be disengaged from the control valve seat when the control plug is in the on position, thereby allowing fluid communication between the control channel and the control port. ### Claim 4 (depends on 3) A cylinder valve assembly as defined in claim 3 further comprising a control plug lateral seal disposed about the control plug and configured to seal the control port from fluid communication with an ambient environment. ### Claim 5 (depends on 2) A cylinder valve assembly as defined in claim 2 further comprising a valve pin radial seal for preventing fluid communication between the intermediate chamber and the probe chamber independently of the control port, the valve pin slidably extending through the valve pin radial seal. ### Claim 6 (depends on 5) A cylinder valve assembly as defined in claim 5 further comprising a bypass interface element including (a) a pin relief bore through which the valve pin axially slidably extends, and (b) a bypass transfer port in fluid communication between the control channel and the probe chamber. ### Claim 7 (depends on 6) A cylinder valve assembly as defined in claim 6 wherein the bypass interface element axially retains the valve pin radial seal within an annular channel of the intermediate chamber. ### Claim 8 (depends on 7) A cylinder valve assembly as defined in claim 7 further comprising a retention sleeve and an annular probe seal, the probe seal (a) being axially secured between the retention sleeve and the bypass interface element, and (b) configured to create a fluid seal between a lateral wall of the probe chamber and a connector probe inserted into the probe chamber. ### Claim 9 (depends on 1) A cylinder valve assembly as defined in claim 1 wherein the control plug is threadedly actuatable between the on and off positions. ### Claim 10 (depends on 9) A cylinder valve assembly as defined in claim 9 wherein the control plug includes a tool engagement feature configured to be engaged by a torqueing tool external to the valve body to facilitate the threaded actuation. ### Claim 11 (depends on 1) A cylinder valve assembly as defined in claim 1 further comprising a valve pin axial seal, wherein (a) the proximal chamber includes a valve pin seat, (b) when the valve pin is in the closed position, the valve pin axial seal engages the valve pin seat so as to seal the proximal chamber from fluid communication with the intermediate chamber, and (c) when the valve pin is in the open position, the valve pin axial seal is out of engagement with the valve pin seat so as allow the proximal chamber to be in fluid communication with the intermediate chamber. ### Claim 12 (depends on 11) A cylinder valve assembly as defined in claim 11 further comprising a valve pin spring disposed between a spring seat and the valve pin, thereby resiliently-biasing the valve pin toward the closed position, the resilient bias being configured to be overcome by an axial force exerted by a connector probe inserted into the probe chamber. ### Claim 13 A cylinder valve assembly comprising: a valve body including (a) a probe chamber and a proximal chamber disposed along a main axis, (b) an intermediate chamber extending along the main axis between the probe chamber and the proximal chamber, (c) a control port extending radially of the main axis, (d) a bypass channel in fluid communication between the intermediate chamber and the control port, and (e) a control channel including a control valve seat and being disposed between the control port and the probe chamber;
