Key Features
-
Micron-Level Precision Machining: Ultra-fine grinding surface, ultra-small tolerance, perfectly fit the injector inner cavity, no jamming during high-frequency operation.
-
Strict Return Fuel Calibration: Effectively control injector return fuel volume, solve the problem of excessive return fuel and maintain stable rail pressure.
-
Excellent Wear & Corrosion Resistance: High-hardness alloy material resists long-term high-pressure impact and diesel erosion, extending injector service life.
-
1:1 OEM Interchangeability: Completely consistent with original installation size and working parameters, direct replacement for old valves, no modification needed.
-
High Cost Performance Repair: Replace only the control valve instead of the whole injector, greatly reduce construction machinery maintenance cost.
Solvable Common Faults
-
Injector excessive return fuel and internal pressure leakage
