A valve actuating assembly for actuating an internal valve between a closed position and an open position is provided. The valve actuating assembly comprises a cam holder stem securely connected to a valve body of the internal valve; a cam holder operably coupled to the cam holder stem; a cam operably mounted to the cam holder; an actuating shaft extending through at least a portion of the valve body, rotation of the actuating shaft causing rotation of the cam holder and the cam; and a locking ring configured to rotatably secure the cam holder to the cam holder stem, wherein the actuating shaft is removably coupled to the cam holder such that the actuating shaft can be removed from the valve body while the cam and cam holder remain coupled to the valve body.

Actuating assembly for an internal valve

A valve actuating assembly is provided that comprises a cam holder positioned within a valve body of an internal valve, a cam operably coupled to the cam holder and configured to engage a valve stem of the internal valve for moving the internal valve between a first position and a second position, and an actuating shaft extending through at least a portion of the valve body, rotation of the actuating shaft causing rotation of the cam holder and the cam, wherein the actuating shaft is removably coupled to the cam holder such that the actuating shaft can be decoupled from the cam holder and removed from the valve body, the cam holder and the cam being configured to remain positioned within the valve body when the actuating shaft is decoupled from the cam holder and removed from the valve body.

A CO2 low-pressure shut-off system is described. The low-pressure shut-off system may include a low-pressure shut-off valve including a first valve inlet, a second valve inlet and at least one valve outlet, a solenoid valve including a valve inlet, a first valve outlet, and a second valve outlet. The solenoid may be configured to direct a flow of a pressurized gas from the valve inlet into at least one of the first valve outlet and the second valve outlet. The CO2 low-pressure shut-off system further includes a gas monitor electrically coupled to the solenoid valve. The gas monitor may be configured to transmit one of a first signal and a second signal to the solenoid valve to control the flow of the pressurized gas through the solenoid valve.
