Disassembly and Rebuild Procedure

Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we stock in-house, cutting out OEM lead times.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • 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 operational testing verifies spec-level operation.
