The Injector Valve Stem is a key precision moving part inside the high-pressure common rail injector. It cooperates with valve plates and valve assemblies to control fuel injection switching. It is widely applicable to common rail injectors for commercial vehicles and construction machinery. Manufactured from special wear-resistant steel with precision grinding and matched lapping, it features strict dimensional tolerance and smooth movement. It directly affects injection accuracy and sealing performance, serving as a core replacement part for injector maintenance and assembly.
