A personal valve apparatus may include a nozzle, a valve seat, and a moveable poppet valve. The nozzle may comprise an inner air-flow surface having a nozzle cavity extending through the inner air-flow surface. The valve seat may comprise a seat member disposed at an end of the inner-air-flow surface with the seat member disposed over the nozzle cavity. The moveable poppet valve may be disposed over the seat member and the nozzle cavity. The moveable poppet valve may comprise a convex surface. When the moveable poppet valve is in an open position, the convex surface may be disposed over and apart from the seat member to allow air to flow from the nozzle cavity, against the convex surface, between the seat member and the convex surface, and beyond the seat member. The convex surface of the poppet valve may reduce air turbulence, drag, flow separation, and/or noise within the valve apparatus.
