When the CDHS-3 on the 302AF fueling and defueling valve trips, where does the pressure travel?

• A. Directly to the refueling section of the valve
• B. Directly to the diaphragm chamber of the auxiliary Hytrol valve
• C. Through the CDHS-3 to the refueling section of the valve
• D. Through the CDHS-3 to the auxiliary hytrol cover chamber valve

Answer: (D)

When the CDHS-3 on the 302AF fueling and defueling valve trips, the pressure is routed through the CDHS-3 to the auxiliary hytrol cover chamber valve. This process is essential for the operation and safety of the fueling system. In the event that the CDHS-3 trips, it serves as a control mechanism that directs pressure to the appropriate areas to ensure that the valve operates correctly, particularly in preventing over-pressurization or ensuring proper shut-off. The auxiliary hytrol cover chamber valve is designed to manage fluid dynamics within the system effectively, allowing the fuel to be either diverted or shut off as needed. This routing is crucial because it allows for controlled pressure management and protects system components from the risks associated with uncontrolled fuel flow or pressure changes. The correct operation of this function is vital for maintaining safety standards during fueling and defueling operations.
