1. A combined dirt collector and cutout cock device, comprising:
an inlet and configured for interconnection to an air supply;
an outlet configured for interconnection to a control valve of a rail car;
a valve having a valve body coupled to the inlet and the outlet;
a ball with a passageway formed therethrough positioned in a gap formed between a pair of gaskets within the valve body, wherein the ball is moveable between a first position where the passageway is aligned with and places the inlet into fluid communication with the outlet and a second position where the passageway is misaligned with and interrupts fluid communication between the inlet and the outlet and also isolates inlet and the outlet so that any pressure at the inlet is maintained; and
a vent formed in the valve and extending into communication with the gap such that any leaking of pressure from the inlet past the pair of gaskets will be vented.
