    Abstract: A pressure control valve system includes a pressure control valve, an electric actuator, an upstream pressure sensor, a downstream pressure sensor, and a controller. The electric actuator adjustably opens and closes the pressure control valve. The upstream pressure sensor measures pressure upstream of the pressure control valve and outputs a plurality of sequential upstream pressure signals over a plurality of successive periods in time. The downstream pressure sensor measures pressure downstream of the pressure control valve and outputs a plurality of sequential downstream pressure signals over the plurality of successive periods in time. The a controller receives the upstream and downstream pressure signals and outputs a plurality of sequential command signals to the electric actuator. Each sequential command signal is based on a respective one of the plurality of sequential downstream and upstream pressure signals for a respective one of the plurality of successive periods in time.

    Abstract: A transportation refrigeration system includes a transportation refrigeration unit, a gas circuit connected to the transportation refrigeration unit and arranged to connect thereto a split bottle gas supply having a plurality of electric lock-off valves, and a controller. The controller is operably connected to the transportation refrigeration unit and is responsive to instructions recorded on a memory to close the electric lock-off valves of the split bottle gas supply. The instructions also cause to the controller to receive a first measurement of gas pressure in the gas circuit, open a first of the electric lock-off valves of the split bottle gas supply, receive a second measurement of gas pressure in the gas circuit, and determine health of the first electric lock-off valve using the first and second measurements of gas pressure in the gas circuit. Related methods and computer program products are also described.
