Abstract
A cylinder valve assembly includes an actual on-off control subsystem. 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.
