Compressed gas cylinder actuation device

A system, comprising:

• a cylinder having an opening;
• a fracture disk coupled to the cylinder and over the opening;
• an actuator configured to break the fracture disk, the actuator comprising:
• an actuation chamber configured to receive pressurized gas, the actuation chamber is partially defined by a top wall and a bottom wall;
• a cutter body disposed within the actuation chamber between the top wall and the bottom wall, the cutter body including a top portion and a bottom portion;
• a cutting edge extending from the bottom portion of the cutter body and configured to break the fracture disk in response to moving in a first direction;
• a spring disposed between the top portion of the cutter body and the bottom wall of the actuation chamber;
• and
• a pressure cartridge coupled to the actuation chamber and configured to actuate the cutter body, the pressure cartridge including;
• a pressure cavity;
• a fill valve configured to introduce air into the pressure cavity;
• an air channel coupled to the actuation chamber;
• a plunger disposed between the pressure cavity and the air channel, the plunger configured to seal the air channel when in a closed position and to allow pressurized air to flow through the air channel into the actuation chamber in an open position;
• and
• a pressure sensor configured to monitor air pressure in the pressure cavity.
