Rebuild Steps

Our team disassembles each valve to assess internal wear. After ultrasonic cleaning, we install replacements and reassemble and verify operation.

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Teardown: Every valve is disassembled for internal inspection.

Diagnostic Testing

With our 13-stand test facility and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our functional testing verifies consistent performance.
