Rebuild Steps

Every TRUE TRACE 8771AN gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Diagnostic Testing

With over a dozen dedicated flow 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 operational testing verifies spec-level operation.
