Valve Refurbishment Steps

Each valve goes through a full teardown to expose wear and buildup. After cleaning every surface, we replace damaged parts and reassemble the unit to spec.

  • Rigorous Testing: The reassembled unit undergoes rigorous leak and pressure testing to verify it performs to specification.
  • Thorough Decontamination: Every component is put through a deep cleaning process to remove grime and buildup.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing to ensure it meets or exceeds OEM performance specifications.
  • Comprehensive Teardown: Every valve is fully disassembled for a thorough internal inspection.

Our Testing Process

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and additional critical parameters. On request, comprehensive performance reports and detailed graphs are available for purchase. Our pre-shipment testing ensures guaranteed reliability.
