The ND0921001600 fuel injection valve doosan 300 / r340 / zaxis 470 / d-85 is a precision hydraulic flow control component for the DOOSAN 300 / R340 / ZAXIS 470 / D-85, regulating fluid direction and maintaining consistent circuit pressure throughout the hydraulic system. Valve failure leads to hydraulic instability, uncontrolled movement, and pressure loss — conditions that are hazardous to operators and damaging to downstream hydraulic components. Engineered to OEM standard ND0921001600 for precise installation and reliable hydraulic control on the DOOSAN 300 / R340 / ZAXIS 470 / D-85.
Key Features:
- Precise Flow Control: Regulates hydraulic fluid direction and pressure for safe, controlled machine operation.
- OEM Grade Fitment: Manufactured to specification ND0921001600 for direct installation on the DOOSAN 300 / R340 / ZAXIS 470 / D-85 with no hydraulic adjustments required.
- Heavy-Duty Pressure Rating: Built to withstand the high-pressure hydraulic cycles of continuous heavy excavation and lifting work.
The ND0921001600 fuel injection valve doosan 300 / r340 / zaxis 470 / d-85 ensures reliable hydraulic flow control and system pressure stability on the DOOSAN 300 / R340 / ZAXIS 470 / D-85.
What Does This Fuel Pump / Fuel Injection Valve Assembly Do?
The fuel pump draws fuel from the tank and delivers it at the correct pressure to the injection system. The fuel injection valve assembly meters and atomises fuel into the combustion chamber at precisely timed intervals commanded by the ECU, ensuring efficient and clean combustion.
Possible Fuel Pump / Fuel Injection Valve Assembly Problem Symptoms
If your machine is showing any of the following, a faulty fuel pump / fuel injection valve assembly may be the cause:
- Hard starting or extended cranking time before the engine fires
- Black smoke from the exhaust under load, indicating over-fuelling or poor atomisation
- Noticeable loss of power and sluggish response under normal working load
- Engine misfiring or running unevenly at idle or during acceleration
