The Wacker Neuson Injection Valve is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including the HSH350 Hydronic Surface Heater, PT3H trash pump series, E1100 Ground Heater, and the DPU 3050H, DPU 3060H, DPU 3070H, DPU 3750H, and DPU 3760H families of reversible vibratory plate compactors. As a genuine Wacker Neuson part, the is manufactured to the same specification as the original component, ensuring a direct, like-for-like replacement. This valve is built to deliver consistent, metered fuel delivery across a diverse lineup of diesel-powered and heating equipment. If you're servicing an HSH350, a PT3H pump, or any of the DPU H-series compactors, confirming part number against your machine's serial number is the best way to verify fitment before ordering.
Key Features
- Metered Fuel Delivery Accuracy — Precision-engineered to OEM specification, this injection valve maintains correct fuel metering critical to consistent ignition and combustion performance in diesel and heating applications.
- Genuine OEM Part — Sourced directly from Wacker Neuson, part 5000227664 matches the original valve in geometry, material grade, and seating tolerances — no guesswork on fitment or compatibility.
- Broad Cross-Equipment Compatibility — A single part number covering the HSH350 Hydronic Surface Heater, PT3H pump, E1100 Ground Heater, and multiple DPU 3050H through DPU 3760H compactor variants makes this a high-utility stocking part for mixed fleets.
- Protects Combustion System Integrity — A worn or leaking injection valve causes hard starting, rough running, or uncontrolled fuel delivery; replacing it with the correct OEM valve restores clean, controlled combustion cycles.
- Fuel System Safety — Proper valve seating and sealing prevent uncontrolled fuel discharge, which is critical in heating equipment and pump applications where fuel leaks pose a fire or safety hazard.
The injection valve controls the precise delivery of fuel into the combustion chamber or burner assembly of a diesel engine or indirect-fired heating system. It regulates the timing and volume of fuel introduced during each cycle, which directly affects ignition reliability, combustion efficiency, and overall output. When an injection valve begins to wear, leak, or stick, the result is typically hard starting, inconsistent operation, excessive fuel consumption, or a complete failure to ignite — all of which can bring work on the jobsite to a halt. Replacing a faulty valve with a correct OEM-spec unit like the Wacker Neuson 5000227664 restores proper fuel control and protects the broader fuel and combustion system from secondary damage.
