⚙️ Key Features

• Genuine Volvo Penta fuel-filter drain valve
• Used on D9, D11, D12 and D13 fuel systems
• Allows controlled water and sediment drainage
• Seals the lower bowl during normal operation
• Inspect the valve seal and threads at every filter service
• Engine type: Volvo Penta D9, D11, D12 or D13 diesel

🔌 Function

Opens the lowest point of the fuel-filter bowl so water and sediment can be removed during service.

⚠️ Common Signs of Failure

• Pressure or flow outside specification
• Leakage through the valve body or connections
• Valve sticking open or closed
• Repeated alarms, unstable operation or loss of system protection
• Corrosion, contamination or damaged sealing surfaces

🛠️ Service Notes

• Establish what the valve seals against, then drain and depressurise that system before removing it so nothing is lost or spilled into the bilge
• Clean the threads and the sealing face in the housing, fit a new sealing washer or O-ring where one is used, and seal a tapered thread with the product the manual specifies
• Tighten to the figure in the manual while holding the body so the outlet finishes pointing where it needs to for draining, and take particular care in an alloy or plastic housing
• Work the valve fully open and fully shut by hand to check it moves freely and seats, and refit any cap, plug or drain hose the original carried
• Make sure the valve is fully closed and capped before refilling, then run the system and check it for weeps — a drain left cracked open is an easy way to lose coolant or oil at sea
