1. F00RJ00339 Injection Valve Set Introduction
The injection valve set is a critical component of the injector system, comprising the valve stem and valve cap. It is housed in the control room within the injector body and plays a pivotal role in controlling oil injection and return. This set is not only a core component but also prone to high damage rates.
Valve Cap Inspection: Use a microscope to inspect the contact surface between the valve cap and the ball for any signs of damage. If damage is detected, the valve cap should be replaced promptly.
Valve Stem Inspection:
Top of Valve Stem: Examine the top of the valve stem for any surface damage. A change in the original silver color to white indicates damage, necessitating a replacement.
Contact Area with Injector: Similarly, inspect the valve stem’s contact area with the injector for surface damage. Any change from the original silver color to white indicates the need for replacement.
