Shop Stanadyne Delivery Valves for Reliable Diesel Performance

Goldfarb & Associates offers OEM-compatible Stanadyne delivery valves for diesel injection pumps used in agricultural, automotive, and industrial applications.

Find the Stanadyne Valve You Need Fast and Accurately

Goldfarb & Associates stocks a wide range of Stanadyne delivery valves, designed for use with both inline and rotary injection pumps. These valves are essential for regulating high-pressure fuel flow in diesel systems. We supply new, rebuilt, and inspected used valves, each of which is verified against strict OEM specifications for function, fit, and durability.

Our diesel specialists inspect every delivery valve at our Rockville, MD, facility before it is added to inventory or shipped to your door.

Choose From Our Available Stanadyne Delivery Valve Inventory

We maintain one of the largest inventories of Stanadyne-compatible delivery valves in the United States. Our stock covers both rotary (DB, DB2, DB4) and inline applications.

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

Frequently Asked Questions

Are these genuine Stanadyne parts?

Yes. We carry OEM-new and OEM-equivalent rebuilt valves. Used valves are pulled from verified assemblies.

Can I rebuild the delivery valve myself?

It's possible but not recommended, unless you have diesel-specific lapping tools and a test bench. We advise buying rebuilt or new.

Do you offer matching holders or valve kits?

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.

Is there a warranty on rebuilt valves?

Yes. Our satisfaction guarantee backs rebuilt valves. Extended options are available for repair shops.
