Disassembly and Rebuild Procedure

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

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.

Leak and Performance Testing

With thirteen in-house test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our performance testing verifies spec-level operation.

Repair, Rebuild and Exchange Options

Beyond standard maintenance, we offer specialized repairs for your REXROTH 4WS2EB10-45/60B2ET70Z8DM unit. Our overhaul process includes mineral bath cleaning and pressure testing, using only new replacement components.

Stock Availability
