Valve Body Overview:
The valve group is among the components which the greatest demands are placed. The valve group is directly responsible for actuating the nozzle and releasing the correct amount of fuel to be atomized in the combustion chamber.

Bosch never reuses the valve group from the injector core or attempt to correct deficiencies in the used part. This ensures that the operating characteristics and service life of our injectors remain unchanged and uncompromised.
Other brands insert used parts that have discoloration, corrosion and/or pitting. This can cause friction during movement of the valve piston, compromising injector performance.
Armatures in other injectors are repaired by varnishing and cleaning up the armature. This leaves behind corrosion which leads to inconsistent operation.
Competitor Armature
Each Bosch injector is carefully inspected and replaced with a brand new originally manufactured armature.
Bosch Armature
The Armature works in tandem with the solenoid to regulate the opening and closing of the ball sealing surface.
Armature Overview:
This ball seat has been reground to remove wear which will impact the overall injector performance and reduce its service life.

When Bosch replaces the valve body, we also replace the ball seat. We never reuse the valve group from the injector core or attempt to correct deficiencies in the used part. This ensures that sealing within the ball seat remains uncompromised, resulting in optimal performance that is never compromised.

The ball seat sealing surface is critical for injector performance. Abrasive contaminants can erode and damage the ball seat causing the ball not to seal properly, leading to improper injection and hard start conditions.
