1. A valve arrangement for a pressurized fluid source, the valve arrangement comprising:
a valve body comprising a first inlet, a first outlet, and a main fluid channel extending along a longitudinal axis of the valve body;
a spool located in the main fluid channel, the spool configured to translate along the longitudinal axis of the valve body;
an actuation cavity housing configured to be coupled to the valve body, the actuation cavity housing comprising a second inlet, a piston aperture, and an actuation cavity;
a piston rod located at least partially within the actuation cavity, the piston rod configured to extend from the actuation cavity housing at least partially into the main fluid channel to secure the spool in a first position whereby the spool fluidly seals the first inlet from the first outlet; and
a solenoid operated pressure cartridge configured to be coupled to the actuation cavity housing, the solenoid operated pressure cartridge includes a pressure cartridge body defining a self-contained pressure cavity containing the actuation fluid pressure, an inlet, and an outlet, the solenoid operated pressure cartridge further comprising a fill valve disposed at the inlet of the solenoid operated pressure cartridge whereby the self-contained pressure cavity is configured to receive a pressurized fluid from an external fluid source, wherein, in response to the solenoid operated pressure cartridge being energized, the solenoid operated pressure cartridge is configured to release the actuation fluid pressure into the actuation cavity to bias the piston rod to exit the main fluid channel, thereby releasing the spool from the first position to a second position whereby the first inlet is in fluid communication with the first outlet.
