Abstract
A flow control valve to regulate the bleed flow rate of a pressurized vessel at one of only two available bleed flow rates. The flow control valve comprises an axial main gas flow passageway with an integral check valve that allows pressurization of the vessel, a bleed passageway for depressurization of the vessel, and a threaded bleed passageway cap that allows bleeding of the vessel at one of only two rates available, based on the counter-rotated position of the bleed cap.
