Rush and priority service options exist. Availability depends on current workload, so contact us early.

Warranty coverage of a one-year warranty is included with every repair we complete.

It depends on the unit and scope of work. We provide an estimated timeline after initial evaluation.

If the main housing or board is intact, repair is usually the better option. We can restore most units to working condition with tested parts.

We recommend sending pictures, especially if the model number is unclear or there is visible damage.

Rebuild Steps

We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.

  • Teardown: Every valve is disassembled for internal inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Testing and Bench Verification

Each REXROTH 4WH6D53/QMBG24 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our operational testing verifies proper functionality.
