How We Rebuild This Valve

Every REXROTH 4ERAE6 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Hydraulic Testing Process

Each REXROTH 4ERAE6 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our pre-shipment testing verifies spec-level operation.
