Roughness Inspection of Conical Surface in Hydraulic Valve Seat

Executive Summary

Hydraulic systems rely heavily on precision-sealed surfaces such as valve seats, where surface finish plays a crucial role in system reliability and performance. EDM Intelligent Solutions delivers high-resolution, non-contact metrology services for roughness analysis of complex geometries, including conical sealing surfaces. This report details a surface roughness inspection case study using our MVi5 3D Metrology Center on a stainless steel valve seat.

Overview of 3D Metrology Capabilities

Our advanced 3D metrology systems provide micron-level surface and form data without contacting or damaging the part. This is especially useful for hydraulic components, where wear and leakage resistance are tied directly to surface topography.

Key capabilities include:

Non-contact roughness analysis at µm scale
Accurate data acquisition on curved and conical surfaces
Profile extraction and roughness parameter computation
Quantitative metrics for quality control and traceability

Application Case Study: Conical Valve Seat Surface Inspection

Component Overview

Type: Valve Seat
Material: Stainless Steel
Metrology System: MVi5 3D Metrology Center
Metrology Services: Surface Roughness Measurement

Inspection Process

The valve seat’s conical surface was scanned with the MVi5 3D Metrology Center. Roughness profiles were extracted from the 3D scan to quantify Ra, Rz, and other texture parameters. The non-contact nature of the inspection preserved the part’s integrity while delivering precise surface data.

Results & Benefits

Detailed roughness map of conical sealing surface
Confirmed surface finish within specification
Eliminated need for destructive testing or replicas
Improved confidence in sealing performance and reliability

Conclusion

Precision surface finish measurement is vital for high-performance hydraulic systems. EDM Intelligent Solutions’ non-contact 3D metrology tools enable accurate inspection of complex conical features—critical for valve functionality and longevity.
