What is the method to manually close the hydraulic SOV?

The method to manually close the hydraulic Shutoff Valve (SOV) involves using both the HYD SOV button and the Engine fire push button. When the HYD SOV button is activated, it initiates the command to close the hydraulic shutoff valve, which is essential for controlling hydraulic systems in the event of a malfunction or emergency. Additionally, the Engine fire push button serves a dual purpose: it not only helps manage fire suppression but also closes the hydraulic shutoff valve associated with the engine being shut down. By using both of these buttons, the hydraulic system can be effectively isolated to prevent further issues, giving the operator complete control in critical situations.

The inclusion of both buttons ensures a comprehensive approach to safety and system management, illustrating the importance of having multiple access points for shutting down systems in emergencies.
