How We Rebuild This Valve

The NACHI DAX 111B is powered up on a controlled test bench where we monitor outputs, check voltage rails, and trace faults to the component level before replacing anything.

  • Sourced Components: Replacement parts are sourced from our inventory or reliable suppliers for a quality repair.
  • Static-Safe Environment: All work is performed in an ESD-safe environment to protect sensitive electronic components.
  • Component-Level Diagnostics: We test individual resistors, capacitors, and ICs to pinpoint the exact source of the problem.
  • Trace and Signal Analysis: We analyze the circuit board for broken traces or weak signals that could cause intermittent faults.

The repaired NACHI DAX 111B is put through power-on tests and load simulations to confirm that all functions are restored and the unit operates reliably. Our system integration analysis confirms proper functionality.
