1140125 Ball Valve | Genuine Volvo Penta Part

🔧 Product Description

This is the genuine Volvo Penta 25 mm ball valve (part number 1140125), a cooling system shut-off valve used to isolate raw-water or coolant lines for servicing and winterisation. The D=25 mm bore is what separates this valve from other ball valves sharing the same name, so confirm the line size before ordering. It supersedes earlier part numbers 21165588 and 828239, giving it broad coverage across Volvo Penta marine diesel installations.

🔌 Function

The ball valve provides a quarter-turn shut-off in a cooling system line, allowing water flow to be stopped for service, draining or winterisation. When open it gives a full-bore flow path with minimal restriction to cooling circulation.

⚠️ Common Signs of Failure

• Handle stiff, seized or impossible to turn through a full quarter turn
• Weeping or dripping from the valve stem or body joints
• Valve fails to fully seal when closed, allowing water past the ball
• Visible corrosion, scaling or salt deposits restricting the bore
• Reduced coolant or raw-water flow with the valve in the fully open position

🛠️ Service Notes

• Fit the valve so the handle is accessible and can swing through its full travel, and so any flow direction marking on the body is respected
• Hold the valve body with a spanner while tightening pipework into it, rather than taking the load through the valve itself
• Use only a sealing method suited to the thread form, applied sparingly so nothing can be carried into the bore
• Open and close the valve fully several times after fitting and check for leaks under working pressure; a ball valve should be left fully open or fully shut, never part open as a throttle
• Exercise the valve at regular intervals in service — the one left in the same position all season is the one that seizes when you need it
