How does a dash valve work?

A dash valve is a type of valve that is typically used in semi trucks to control the air supply for the parking brake and the trailer air supply. The dash valve is typically mounted on the dashboard of the truck and is operated by the driver.

When the driver wants to release the parking brake, they will turn the dash valve to the "release" position, which allows air to flow into the brake system and release the brake. When the driver wants to apply the parking brake, they will turn the dash valve to the "apply" position, which cuts off the air supply to the brake system and activates the brake.

The dash valve also has a position for controlling the air supply to the trailer. When the driver wants to connect the trailer air supply, they will turn the dash valve to the "trailer" position, which allows air to flow from the truck's air compressor into the trailer's air system. When the driver wants to disconnect the trailer air supply, they will turn the dash valve to the "disconnect" position, which cuts off the air supply to the trailer.

Overall, the dash valve is an important component in the air brake system of a semi truck, as it allows the driver to control the air supply for the parking brake and the trailer air supply.

What is tractor protection control valve?

A tractor protection control valve is a type of valve that is used in semi trucks to protect the tractor's (i.e., the main vehicle) air brake system and other air systems in the event of a trailer breakaway or major air leak. The valve is typically mounted on the tractor and is connected to the trailer's air brake system via an air hose.

The tractor protection control valve is designed to automatically cut off the air supply to the trailer's brakes in the event of a trailer breakaway or major air leak. This helps to prevent damage to the tractor's air brake system and other air systems, and ensures the safety of the tractor and its occupants.

In the event of a trailer breakaway, the tractor protection control valve will automatically cut off the air supply to the trailer's brakes, allowing the tractor to continue moving without the trailer. This can help to prevent accidents and injuries.

In the event of a major air leak, the tractor protection control valve will also automatically cut off the air supply to the trailer's brakes, allowing the tractor to safely come to a stop. This can help to prevent accidents and injuries, as well as damage to the tractor's air brake system and other air systems.
