Understand the Role of Your Stanadyne Delivery Valve

The delivery valve in a Stanadyne pump controls the final flow of fuel from the plunger chamber to the assembly line. Its purpose is to:

• Stop injection cleanly by reducing line pressure

• Prevent dribbling and emissions spikes

• Maintain proper pump-to-nozzle fuel delivery timing

• Improve combustion consistency across cylinders

• Control hydraulic pulse damping in the line

Yes. We supply holders, seats, springs, and seals that work with most Stanadyne pump types.

What if I don't have a part number?

Send a pump tag photo or describe your engine and application—we'll match it using our reference data.
