Purpose
Controls outflow in the colony's gas or ventilation system; simultaneous activation with inflow valve overloads pressure, sabotaging Macra-controlled infrastructure
Significance
Ben's activation breaks his Macra conditioning, commits him to the Doctor's plan, and risks colony collapse to disrupt enemy control—pivotal in the fight for freedom
