How We Rebuild This Valve

Each MITSUBISHI MR-J20A control unit is diagnosed using schematics and specialized test equipment to find the root cause of the failure before any repair work begins.

  • Trace and Signal Analysis: We analyze the circuit board for broken traces or weak signals that could cause intermittent faults.
  • Sourced Components: Replacement parts are sourced from our inventory or reliable suppliers for a quality repair.
  • Professional Rework: Failed components are carefully desoldered and replaced by our experienced technicians using modern rework stations.
  • Static-Safe Environment: All work is performed in an ESD-safe environment to protect sensitive electronic components.

Hydraulic Testing Process

After repair, the unit is connected to a dedicated test rig where we simulate real-world inputs and verify that outputs match published specifications. Our functional analysis confirms spec-level operation.
