The bow drainage remote control system consists of a valve remote control box, a stem processing unit, an electric remote control butterfly valve, and a valve electric actuator. The valve remote control box is installed in the cab, engine room control room, or other living areas. The box processing unit is installed in the box cabin, and the valve remote control box sends control instructions according to the working conditions of the ship. After centralized processing by the box processing unit, it drives various electric remote butterfly valves and valve electric actuators to operate. When each valve reaches the specified position, it automatically stops running and sends a position signal feedback to the valve remote control box, achieving remote indication of valve position. By adopting computer digital communication technology, a significant amount of cable and construction costs can be saved.
