⚙️ Key Features

• Designed for the fuel-filter and water-separator assembly
• Allows controlled draining of water and contamination from the separator
• Engine type: Volvo Penta D5/D7 industrial diesel engine family

🔌 Function

Allows water and contamination to be drained from the fuel-filter or water-separator assembly.

⚠️ Common Signs of Failure

• Diesel fuel or water leaks from the valve when closed
• The valve is blocked by sediment or corrosion
• The valve cannot be opened or closed smoothly
• The separator cannot be drained completely
• Threads, seals or the valve body are cracked or damaged

🛠️ 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
