How We Rebuild This Valve

We disassemble every valve, inspect it inside and out, and clean all moving parts. Components that fail inspection are swapped out before the valve is rebuilt and tested.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Teardown: Every valve is disassembled for internal inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Diagnostic Testing

With thirteen in-house test stands 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 performance testing verifies spec-level operation.
