A cryogenic cylinder control system for regulating fluid within a cryogenic cylinder, the cryogenic cylinder control system comprising:
- a pressure relief and vent module fluidly connected to a head space above liquid within the cryogenic cylinder;
- a manual valve module fluidly connected to the liquid within the cryogenic cylinder and to an external device, wherein the manual valve module comprises a first value comprising a first valve inlet and a first valve outlet, wherein the first valve is movable between a first valve open configuration and a first valve closed configuration to control fluid between the first valve inlet and the first valve outlet, wherein the first valve inlet is fluidly connected to the liquid within the cryogenic cylinder;
- a build-up coil fluidly connected to the manual valve module, wherein the first valve outlet is fluidity connected to a build-up coil inlet of the build-up coil;
- a solenoid valve module fluidly connected to the manual valve module, the head space within the cryogenic cylinder, and the build-up coil, wherein the solenoid valve module comprises:
- a solenoid valve module valve body that defines:
- a solenoid valve module inlet that is fluidly connected to a build-up coil outlet of the build-up coil;
- a solenoid valve module outlet;
- and
- a solenoid valve module combination inlet/outlet that is fluidly connected to the head space within the cryogenic cylinder;
- and
- a first solenoid valve that is movable between a first solenoid valve closed configuration in which the first solenoid valve prevents fluid from flowing from the solenoid value module inlet to the solenoid valve module combination inlet/outlet and a first solenoid valve open configuration in which the first solenoid valve enables fluid to flow from the solenoid valve module inlet to the solenoid valve module combination inlet/outlet;
- and
- a controller operatively connected to the solenoid valve module to control fluid flow through the solenoid valve module,
- wherein the first valve, the build-up coil, and the first solenoid valve form pressure-building circuit, and
- wherein when the first valve is in the first valve open configuration and the first solenoid valve is in the first solenoid configuration:
- the liquid flows from the cryogenic cylinder through the first valve to the build-up coil inlet,
- the build-up coil vaporizes the liquid into gas,
- the gas flows from the build-up coil outlet to the solenoid valve module inlet,
- the gas flows from the solenoid valve module inlet to the solenoid valve module combination inlet/outlet, and
- the gas flows from the solenoid valve module combination inlet/outlet to the head space within the cryogenic cylinder.
