A320 : MANUAL REFUEL VALVE OPERATION

 MANUAL REFUEL VALVE OPERATION

During refueling, the refuel valve solenoid is energized and fuel pressure from the tanker/pump unit opens the valve. If the solenoid fails or if the electrical control of the solenoid fails, the valve may be operated manually by a plunger on the valve. There are 3 refuel valves on the aircraft. 

Location of Refuel Valve : The center tank valve is located in the R/H wheel well on the forward wall (which is actually the center tank rear spar). The wing tank refuel valves are located on the left and right wing leading edge near the refuel coupling (wing access panel 522JB and 622JB respectively) .

Operation :  To refuel a tank, PUSH and HOLD the manual plunger on the valve. The fuel pressure from the tanker/pump unit will open the valve. Be sure to monitor the fuel quantity carefully using the normal indication system or the MLI's if electrical power is not available. When the desired quantity is reached, release the plunger to close the valve.

NOTE : The most important thing to remember is that there is NO High Level protection when operating the refuel valve with the manual plunger.

Personnel Required : Preferably Three competent person are required for effective function. One Person should control the refuel valve manual plunger and maintain positive communication with fuel truck operator and intercom guy, One  Person in cockpit to monitor the ECAM fuel page for correct quantity and one Person on ground intercom to relay message between cockpit and ground fueling. 

NOTE : Check Inter cell transfer valve for closed position before refueling. If open FQIC reset required. Follow AMM for further steps Centre tank pumps/transfer valves to be OFF (Preferred all Fuel pumps OFF) MODE SEL P/B in AUTO Crossfed (XFEED) P/B in OFF.
