The valve that closes off the trachea is called the epiglottis. It is a flap of cartilage located at the base of the tongue that covers the trachea during swallowing, preventing food and liquid from entering the airway. This protective mechanism helps ensure that air passes into the lungs while food and drink are directed into the esophagus.

What is the difference between a fail open valve and a fail closed valve?
Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.

Difference between butterfly valve and gate valve?
Butterfly valve refers to a kind of valve whose closing part (butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The butterfly valve is usually 90° from fully open to fully closed. The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The advantages of the gate valve: small fluid resistance, less effort to open and close, no restriction on the flow of the medium, no turbulence, no pressure reduction

What is meant by air to open valve?
An increase in air pressure to the actuator is required to cause the valve to open. This is called Air-to-Open Valve. Otherwise normally called Fail-Closed or Normally Closed Valve. An increase in air pressure to the actuator is required to cause the valve to close. This is called Air-to-Close Valve. Otherwise normally called Fail-Open or Normally Open Valve. Another way of looking at these definitions are: When air is given from the bottom of the diaphragm, the stem will go up and flow enters from the input and flows to the output. This is called Air-to-Open. When air is given from the top side of the diaphragm, the stem will go down and the stem will close the plug into the seat, meaning that the flow would be shut-off and the valve will be closed. Basically, you need air to either open or close the valve to allow your flow to proceed or shut.
