Materials:
The valve body is made of high-chromium alloy steel and is integrally quenched and formed. The needle valve assembly undergoes high-precision hydraulic lapping, and the valve seat surface is hardened. It withstands high temperatures and pressures, resists corrosion from mining dust and high-frequency vibrations, and is suitable for heavy-duty, harsh operating conditions.

Repair and Replacement:
Replaces aged or damaged original injectors, effectively resolving issues such as poor atomization, difficult starting, idle vibration, skyrocketing fuel consumption, black exhaust smoke, and lack of power. A standard replacement part for mining and construction sites, it can be installed in-place to save time and effort.

Stringent Quality Control:
All products undergo on-machine testing for injection pressure, atomization quality, and sealing performance. Every parameter meets original factory standards, and all units pass 100% final inspection before shipment. Available in both new and remanufactured specifications to accommodate bulk purchases by repair shops and equipment maintenance needs.
