A check valve can include a pressure actuator or an electromagnetic actuator. The check valve includes a valve inlet, a valve outlet, and flap disposed between the valve inlet and the valve outlet. The check valve has an open state and a closed state. The pressure actuator in fluid communication with the valve inlet. The check valve has an open state and a closed state. The check valve is configured to allow an input gas to flow from the valve inlet to the valve outlet when the check valve is in the open state. The check valve is configured to preclude the input gas from flowing from the valve inlet to the valve outlet when the check valve is in the closed state. Upon actuation of the pressure actuator or the electromagnetic actuator, the flap moves away from the valve inlet to allow the inlet gas to move from the valve inlet to the valve outlet. |
