COMB. VALVE 3V MANUAL 1/4

Function and technical context

This three-way fuel valve with manual operation and 1/4" connection is part of the fuel supply system of marine engines, allowing you to select, divert or cut off the fuel flow between different tanks or circuits of the boat. Its three-way manual mechanism offers the skipper direct control over fuel distribution without depending on electrical actuators, making it a highly reliable component in nautical installations. A failure in this valve can cause interruptions in the fuel supply, unwanted circuit mixtures or leaks that compromise both engine performance and safety on board. The reference GS31010 identifies this unit precisely to ensure compatibility with your existing installation.

When to replace this part?

The most common symptoms of deterioration in a three-way fuel valve are fuel leaks in the body or fitting area, excessive resistance or the impossibility of turning the selection lever, and intermittent engine cuts due to insufficient or irregular fuel flow. It is recommended to visually inspect the valve during each seasonal maintenance, checking the condition of the internal seals and the tightness of the connections. Preventively replacing a valve with signs of wear or leaks prevents unexpected engine stops while sailing and reduces the risk of fire on board due to fuel leaks.
