Reconditioning Capabilities
Fuel Valve Reconditioning
We specialize in restoring fuel valve components to optimal performance and extended service life with a precise, repeatable process.
We specialize in restoring a wide range of fuel valve components to optimal performance and extended service life.
Every part is inspected against strict workshop criteria before reconditioning begins, helping ensure durability, sealing performance, and dependable operation in demanding environments.
Blueprint-tested
Measured and documented
Engine maker requirements followed
Components include:
Atomizer
Spindle & Guide
Non-return Valve
Auxiliary Fuel Injectors
Atomizer
The correct spray pattern is essential for efficient combustion, fuel economy, and engine performance. Every atomizer is carefully tested and adjusted to meet required standards.
Spindle & Guide
Accurate contact angles between the spindle and guide are critical for proper sealing. Precision grinding and inspection ensure tight sealing and reliable operation.
Non-Return Valve
During final atomization testing, the opening pressure is accurately set to manufacturer requirements for consistent fuel delivery.
Auxiliary Fuel Injectors
Auxiliary engine fuel injectors are fully reconditioned with precision grinding, component renewal, pressure setting, and spray testing to ensure reliable daily engine operation.
Precision engineering & testing
Advanced Precision & Inspection
Specialized grinding, blue printing methods, and final measurement checks ensure accurate sealing and documented performance.
The sealing face and seating areas of components are processed using specialized grinding machines to ensure precise alignment and sealing performance.
For optimal results, the grinding angles between spindle and seat are slightly different, helping deliver improved seating accuracy during the reconditioning process.
Guide angle
60°
Spindle angle
60°40′
Each reconditioned component is inspected using blue printing methods, and final clearance and lift are measured and documented. Atomization performance is tested according to engine manufacturer requirements.
Inspection checkpoints
Grinding angles are controlled to maintain precise seating alignment and sealing performance.
Blue printing methods verify contact patterns and help confirm the quality of the reconditioned surface.
Final clearance, lift, and atomization checks are measured, recorded, and documented.
Testing follows engine maker requirements to support dependable real-world operation.
