Abstract
The dual vent valve includes a housing having brake pipe, emergency input and exhaust ports, and first and second valves. The emergency output port is fluidly connected to the emergency input port. The first valve selectively connects the brake pipe port to the exhaust port by opening the first valve in response to an emergency signal on the brake pipe port. The second valve selectively connects the brake pipe port to the exhaust port by opening the second valve in response to an emergency signal on the emergency input port.
