A personal valve apparatus includes an air inlet, an air outlet, a nozzle, a valve seat, and a moveable poppet valve. The nozzle comprises an inner air-flow surface having a nozzle cavity, extending along the inner air-flow surface, in communication with the air inlet. The valve seat comprises a seat member disposed over the nozzle cavity at the air inlet. The moveable poppet valve is disposed over the seat member and the nozzle cavity at the air inlet. The moveable poppet valve comprises a convex surface. When the moveable poppet valve is in an open position, the convex surface is disposed over and apart from the seat member at the air inlet and configured to allow air to flow from the air inlet, against the convex surface at the air inlet, between the seat member and the convex surface at the air inlet, into and through the nozzle cavity, and out of the air outlet.
