What is the function of the Astern Throttle valve?

The Astern Throttle valve primarily controls the flow of steam to the propulsion system, allowing the ship to move in the reverse direction. When the Astern Throttle valve is opened, it enables the turbines to receive the necessary steam, thereby reversing the direction of the propulsion system and propelling the ship aft. This function is crucial for maneuverability, especially when docking or navigating in confined waters.

The design and operation of the Astern Throttle valve are essential for effective ship control, ensuring that the vessel can safely and efficiently transition from forward to reverse propulsion as needed during operations.
