Additional part numbers and cross-references are available on request. All delivery valves are tested for seat sealing, spring tension, and flow regulation.

What Is a Denso Delivery Valve?

A delivery valve regulates fuel pressure and flow from the injection pump to the injector. In Denso injection systems, the delivery valve:

• Controls injection timing

• Prevents pressure backflow

• Maintains consistent fuel volume

• Reduces secondary injection effects

Failing or leaking delivery valves can cause hard starting, excessive smoke, injector knock, and issues with fuel return pressure.

What Diesel Engines Use Denso Delivery Valves?

Goldfarb & Associates provides Denso delivery valves for engines from:

• Toyota (2L, 3L, 1KZ-TE, 1KD-FTV)

• Isuzu (4JJ1, 4HK1, 6HK1)

• Hino (J05, J08, N04C)

• Mitsubishi Fuso (4M50, 6M60)

• Kubota, Yanmar, and Case IH applications

• Light commercial and agricultural diesel platforms

We provide fitment support for both pre-common-rail and common-rail Denso systems.

What Types of Denso Delivery Valves Are Offered?

We stock delivery valves in three categories:

• New OEM Valves – Unused, direct-from-manufacturer units

• Rebuilt Valves – Restored with new springs, seals, and precision-lapped seats

• Used Valves – Inspected for wear, tested for spring response, and valve seat integrity

Each valve is flow-verified, cleaned, and checked for leak-free sealing.

How to Choose the Right Denso Delivery Valve?

To identify the correct part, you'll need:

• OEM part number (e.g., 096420-0320)

• Injection pump model (e.g., VE, HP3, HP4, ZEXEL-Denso)

• Engine model (e.g., Toyota 2L-T, Hino J08C)

• Vehicle or equipment application (e.g., truck, tractor, genset)

If part numbers are unavailable, send us your pump code and engine serial number, and we'll match it for you.

Why Are Denso Delivery Valves Critical to Injection Performance?

The Denso delivery valve plays a central role in fuel metering and pressure drop control. Faulty valves can cause:

• Excessive return line pressure

• Injector dribble and secondary combustion

• Loss of injector pop pressure

• Poor idle and rough acceleration

Replacing the delivery valve restores fuel system timing and improves overall diesel combustion efficiency.
