  • Choked flow doesn't need theHeimlich maneuver
    travel backwards fast enough to influence the upstream flow. By controlling upstream pressure, the valve can deliver gas with a stable flow rate. A ball in the valve opening, for instance, can be adjusted to control upstream pressure. Designers have two options when dealing with choked-flow valves...
