Rebuild Steps

Every ABEX 425-1326 P/N 77031 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Teardown: Every valve is disassembled for internal inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • 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 pre-shipment testing verifies proper functionality.
