1. A control device comprising:
a control unit including an inlet port, an outlet port, a diaphragm located between the inlet port and the outlet port, where the control unit is configured to maintain a flow of fluid from a variable pressure fluid source;
a first control device outlet which is configured to receive a first fluid flow from the outlet port;
a second control device outlet which is configured to receive a second fluid flow from the outlet port;
a transportation unit including a barrier element with an opening, where the opening allows a flow;
a blockage device configured to close the opening to prevent the flow, where a force derived from the prevented flow holds the blockage device in place relative to the opening to prevent the flow;
a stationary movement device configured to roll the blockage device to a first position relative to the opening which allows for a passage of the flow through the opening in the barrier element.
