Full model list at the end of this description.

## ⚙️ Key Features

-   Genuine Volvo Penta valve
-   Correct pressure or flow characteristic
-   Factory thread and connection geometry
-   Maintains the intended circuit behaviour
-   Single valve; fittings and sealing washers are separate unless listed
-   Engine type: Volvo Penta 10.8-litre inline six-cylinder industrial diesel

## 🔌 Function

Regulates return flow so the low-pressure fuel circuit retains the pressure required for stable starting, idle and load operation.

## ⚠️ Common Signs of Failure

-   Incorrect circuit pressure or unstable operation
-   Hard starting, poor performance or delayed response
-   Leakage around the valve or connections
-   Valve stuck open, closed or partially restricted
-   Contamination, corrosion or damaged sealing surfaces

## 🛠️ Service Notes

-   Treat it as a sealed, non-adjustable unit — renew it rather than attempting to clean, shim or adjust the internals
-   Work clean: cap the openings, wipe the area down before opening the fuel system, and do not let dirt or fibres into the fuel side while the valve is off
-   Renew the sealing washers, O-rings or gasket that come with the valve, and never reuse a crushed copper or aluminium washer
-   Tighten to the figure in the workshop manual for your engine; these valves screw into fuel housings and heads that strip readily
-   Bleed and prime the fuel system as the manual for your engine describes, then run the engine and check the joint for weeping under working pressure
