Disassembly and Rebuild Procedure

Our team disassembles each valve to assess internal wear. After ultrasonic cleaning, we install replacements and reassemble and verify operation.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Teardown: Every valve is disassembled for internal inspection.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.

Leak and Performance Testing

Each REXROTH 4WE10G11/LW120-60NAV is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our functional testing verifies spec-level operation.
